To date, these are the only moving structures seen in spatially resolved imagery of debris disks. The surface brightness, number, morphology, and velocities of these moving features constrains their physical location and mass, and thus are critical quantities needed to constrain the origin of this phenomenon. We propose 7 orbits of HST/STIS time per cycle, for cycles 27, 28, 29, to determine: a) What is the surface brightness of all features, and how does the surface brightness and morphology of features change over time?; b) What is the detailed vertical motion of features, and does the amplitude of this motion depend on stellocentric separation?; and c) What is the motion of the newly found features (NW-gamma and NW-delta) on the NW-side of the disk? These data will be used to test hypotheses that predict features are caused by the stellar wind expelling grains originating from a parent body that orbits at 8+/-2 au (Sezestre+ 2017) or by interaction between the star's wind and repeated dust avalanche events (Chiang & Fung 2017). ------------------------------------------------------------------------------------ Observations Description ------------------------ OVERALL PROGRAM This program will obtain two sets of visits of observations of AU Mic. The first set of 4 visits utilize Wedge A0.6 and Wedge A1.0 observations. All visits during this set MUST be executed in contiguous orbits. The second set of 3 visits utilize BAR5 observations. All visits during this set MUST be executed in contiguous orbits. 16205( 6) - 13-May-2022 17:23:06 - [ 2] VISITS AND EXPOSURE DETAILS 1) WEDGE-A OBSERVATION SET Guide Star Acquisitions: We require pointing and roll control with 2-FGS guiding. Single-FGS guiding does not offer sufficient target position stability for coronagraphy. Each visit (after its Guide Star acquisition) begins with a mode-2 target acquisition, is followed by a sequence of repetitive "short" exposures (by CR-SPLIT or exposure replication) at the WedgeA0.6 position followed by a sequence of repetitive "long" exposures (also by CR-SPLIT or exposure replication) at the Wedge A1.0 position. 1) Target Acquisitions. We expose our TA images to a SNR > appx 100 using the STIS ETC. While robust target acquisition is enabled with SNR 40, we also use the TA images as a pre mode-2 astrometric anchor to assess the "behind the wedge" target position to high precision (separate from "diffraction spike" analysis, for which higher SNR for precision centroiding is required. We also use these F25ND3 filtered imagesto photometrically obtain target:PSF template brightness ratios in the broad STIS passband. The STIS Target Acquisition ETC was used to determine the eposure times for all acquisition images. 2) The "short" exposure times are designed to reach 90% of full-well depth, with the target coronagraphically occulted, at the edge of the wedge 0.3" from the star. We scale, using the ETC, this from observations predicated upon an A0 star with V = 3.55 reach 90% full well from the PSF halo in 1 second based upon preious STIS coronagraphic observations allowing for up to as much of 1/2 pixel of possible target decentering in acquisition performance. We generally repeat these exposures to fill appx 35% of the target visibility interval after subtracting the time required for the preceding guide star and target acquisitions. 3) Following the short exposures we execute a Type-2 slew (by a change in instrument aperture to Wedge1.0) for the "long" exposure imaging. Sub-Array Readouts. For most coronagraphic exposures we use subarray readouts (SIZEAXIS2) symmetrically centered on the target to fully read-out the region along the wedge (Axis2, image Y axis) to the edge of the FOV at the small end of the wedge taper, and symmetrically on the diametrically opposing side. For WedgeA1.0 the max SIZEAXIS2 (without displacing with an |unsupported| CENTERAXIS2) is 427 pixels. This implies that the A1.0 position is 10.82 from the edge of the FOV (whole sub-array centered on target symmetrically 21.65 along the wedge). For WedgeA0.6 is (without displacing with an |unsupported| CENTERAXIS2) is 137 pixels. This implies that the A0.6 position is 3.47 from the edge of the FOV (whole sub-array centered on target symmetrically 6.95 along the wedge). VISIT LINKAGES (RELATIVE ORIENTATION CONSTRAINTS AND INTERLEAVED PSF OBSERVATIONS) ============================================================ 16205( 6) - 13-May-2022 17:23:06 - [ 3] We place an absolute orient request on VISIT 2 that constrain the AU Mic disk to align perpendicular to the long axis of occulting Wedge A. We place relative orient constraints on VISIT 1 (-30 to -20 degrees from VISIT 2) and on VISIT4 (20 to 30 degrees from VISIT 2). No relative orient constraints are placed on VISIT 3, where the PSF star is observed. We require all 4 visits within this observation group be executed in contiguous orbits. 2) BAR5 OBSERVATION SET Guide Star Acquisitions: We require pointing and roll control with 2-FGS guiding. Single-FGS guiding does not offer sufficient target position stability for coronagraphy. Each visit (after its Guide Star acquisition) begins with a mode-2 target acquisition, is followed by a sequence of repetitive "short" exposures (by CR-SPLIT or exposure replication) at the nominal BAR5 position. To mitigate against target centering uncertainties behind BAR5, we also include one sequence of repetitive exposures with the target offset by 0.25 pixels ABOVE the nominal center of BAR5 and one sequence of repetitive exposures with the target offset by 0.25 pixels BELOW the nominal center of BAR5 (i.e. an effective dither about the center position of BAR5). We achieve this dither pattern by using a 0.25 pixel dither perpendicular to the BAR5 long-axis (via POS TARG offsets of x = + 0.0024921 arcsec and y = + 0.0122491 for the PLUSDITHER position, and x = - 0.0024921 arcsec and y = - 0.0122491 for the MINUSDITHER position). 1) Target Acquisitions. We expose our TA images to a SNR > appx 100 using the STIS ETC. While robust target acquisition is enabled with SNR 40, we also use the TA images as a pre mode-2 astrometric anchor to assess the "behind the wedge" target position to high precision (separate from "diffraction spike" analysis, for which higher SNR for precision centroiding is required. We also use these F25ND3 filtered imagesto photometrically obtain target:PSF template brightness ratios in the broad STIS passband. The STIS Target Acquisition ETC was used to determine the eposure times for all acquisition images. VISIT LINKAGES (RELATIVE ORIENTATION CONSTRAINTS AND INTERLEAVED PSF OBSERVATIONS) ============================================================ We place an absolute orient request on VISIT 6 that constrains the AU Mic disk to align perpendicular to the long axis of occulting BAR5. We place relative 16205( 6) - 13-May-2022 17:23:06 - [ 4] orient constraints on VISIT 5 (-6.5 to -6.5 degrees from VISIT 6) and on VISIT 7 (6.5 to 6.5 degrees from VISIT 6). We require all 3 visits within this observational be executed in contiguous orbits. -------- Realtime Justification -------- We have no real-time requirments. ------ Calibration Justification ------- We ask for no SPECIAL calibrations for this proposal (and called none out in Phase 1). We did not because we ASSUME that STScI will acquire GAIN=4 (supported mode) bias, DARK, and flat-field frames (and derived hot/bad pixel maps) as part of their Cycle 28 calibration plan in support of approved Cycle 28 science programs. If this is NOT the case then we must obtain GAIN=4 calibration reference bias/dark data as part of our program using NON-POINTED (internal) orbits only. If STScI does not include acquiring for broader purposes the reference data we need, then we will need to add those internal calibrations to this program AFTER the Phase 2 deadline. ------------------------------------------------------------------------------------ 16205( 6) - 13-May-2022 17:23:06 - [ 5] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-AU-MIC STAR, CIRCUMSTELLAR RA=20H45M9.5323S +/- 0.1", J2000 V = 8.627 MATTER, M V-IV DEC=-31D20'27.23" +/- 0.1" Reference Frame: ICRS Comments: Coordinates are from GSC2.3.2.

This set of visits (1-4) uses WedgeA. These visits (1-4) MUST be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: We have set the allowable orientation to range from -30 deg to -20 degrees from Visit 2, to allow a sufficiently large scheduling window. NOTE TO PC: Our science is optimized if we can achieve an orient as close as possible to -30 degrees from the preferred absolute orient of 83.7 degrees in Visit 2. We ask that you please try to identify scheduling windows that enable us to get as close as possible to this orientation. IF the absolute orient of Visit 2 deviates from 83.7 degrees, PLEASE ask us for guidance as to the orientation range we prefer for Visit 1. We absolutely do NOT want the disk major axis (128.7 degrees) to align with the STIS diffration spikes in Visits 1, 2, or 4.

Orientation: We have set the allowable absolute orientation to range from 73.7 deg to 93.7 degrees, to allow a sufficiently large scheduling window. NOTE TO PC: AU Mic's disk has a PA of 128.7 degrees. Our science is optimized if we can achieve an absolute orient that places the major axis of AU Mic's disk perpendicular to the long axis of WEDGEA. We need our absolute orient to be as close as possible to (128.7 degrees + 315 degrees = 83.7 degrees; or equivalently ok 128.7 degrees + 135 degrees = 263.7 degrees). We ask that you please try to identify scheduling windows that enable us to get as close as possible to either of these absolute orientations. These orientiations place the circumstellar disk axis perpendicular to the long-axis of WEDGEA. We have allowed a +/-10 degree window about this strong preference to aid scheduled and GS acquisition.

Orientation: NOTE TO OUR PC: Our PSF star visit (#3) has no absolute or relative orientation constraints. However, all other things being equal, when scheduled, we would request that both be observed with roll angles as close to Visit 2 as possible. This is not a hard requirement and we do not constrain, but a request this if possible to optimize the science return through likely better PSF calibration.

This set of visits (1-4) uses WedgeA. These visits (1-4) MUST be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: We have set the allowable orientation to range from 20 deg to 30 degrees from Visit 2, to allow a sufficiently large scheduling window. NOTE TO PC: Our science is optimized if we can achieve an orient as close as possible to +30 degrees from the preferred absolute orient of 83.7 degrees in Visit 2. We ask that you please try to identify scheduling windows that enable us to get as close as possible to this orientation. IF the absolute orient of Visit 2 deviates from 83.7 degrees, PLEASE ask us for guidance as to the orientation range we prefer for Visit 4. We absolutely do NOT want the disk major axis (128.7 degrees) to align with the STIS diffration spikes in Visits 1, 2, or 4. Relative Timing: This visit (4) MUST immediately follow Visit 3. I.e., They should be executed sequentially in "back-to-back" orbits.

This set of visits (5-7) uses BAR5. These visits (5-7) MUST be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: We have set the allowable absolute orientation to range from 343.7 deg to 15.7 degrees, to allow a sufficiently large scheduling window. NOTE TO PC: AU Mic's disk has a PA of 128.7 degrees. Our science is optimized if we can achieve an absolute orient that places the major axis of AU Mic's disk perpendicular to the long axis of BAR5. We need our absolute orient to be as close as possible to (128.7 degrees + 45 degrees = 173.7 degrees; or equivalently ok 128.7 degrees + 225 degrees = 353.7 degrees). We ask that you please try to identify scheduling windows that enable us to get as close as possible to either of these absolute orientations. These orientiations place the circumstellar disk axis perpendicular to the long-axis of BAR5, while allowing schedulability and avoiding the disk falling along diffraction spikes. We have allowed a +25 and -25 degree window about this strong preference to aid scheduled and GS acquisition. Relative Timing: This visit (6) MUST immediately follow Visit 5 and immediately preceed Visit 7 in back-to-back orbits.

This set of visits (5-7) uses BAR5. These visits (5-7) MUST be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: We have set the allowable orientation to range from -6.5 deg to -6.5 degrees from Visit 6, to allow a sufficiently large scheduling window. NOTE TO PC: Our science is optimized if we can achieve an orient as close as possible to -6.5 degrees from the preferred absolute orient of 353.7 degrees in Visit 6. We ask that you please try to identify scheduling windows that enable us to get as close as possible to this orientation. IF the absolute orient of Visit 6 deviates from 353.7 degrees, PLEASE ask us for guidance as to the orientation range we prefer for Visit 5. We absolutely do NOT want the disk major axis (128.7 degrees) to align with the STIS diffration spikes in Visits 5, 6, or 7.

This set of visits (5-7) uses BAR5. These visits (5-7) MUST be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: We have set the allowable absolute orientation to range from 343.7 deg to 15.7 degrees, to allow a sufficiently large scheduling window. NOTE TO PC: AU Mic's disk has a PA of 128.7 degrees. Our science is optimized if we can achieve an absolute orient that places the major axis of AU Mic's disk perpendicular to the long axis of BAR5. We need our absolute orient to be as close as possible to (128.7 degrees + 45 degrees = 173.7 degrees; or equivalently ok 128.7 degrees + 225 degrees = 353.7 degrees). We ask that you please try to identify scheduling windows that enable us to get as close as possible to either of these absolute orientations. These orientiations place the circumstellar disk axis perpendicular to the long-axis of BAR5, while allowing schedulability and avoiding the disk falling along diffraction spikes.

This set of visits (5-7) uses BAR5. These visits (5-7) MUST be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: We have set the allowable orientation to range from +6.5 deg to +6.5 degrees from Visit 6, to allow a sufficiently large scheduling window. NOTE TO PC: Our science is optimized if we can achieve an orient as close as possible to +6.5 degrees from the preferred absolute orient of 353.7 degrees in Visit 6. We ask that you please try to identify scheduling windows that enable us to get as close as possible to this orientation. IF the absolute orient of Visit 6 deviates from 353.7 degrees, PLEASE ask us for guidance as to the orientation range we prefer for Visit 7. We absolutely do NOT want the disk major axis (128.7 degrees) to align with the STIS diffration spikes in Visits 5, 6, or 7. Relative Timing: This visit (7) MUST immediately follow Visit 6. I.e., They should be executed sequentially in "back-to-back" orbits.
