Note: Due to the geometrical (orientation) restrictions for these observations, the only suitable orientation windows are very quickly approaching, and we really need to know ASAP how that can fit into the existing or soon to be built LRP (long range plan) and conform for those specific orient-constrained dates that guide stars are available. 114435995 ----- Attempting Submission 1 (Thu Nov 19 06:33:56 GMT 2020) ----- ----- Attempting Submission 2 (Fri Feb 12 23:27:01 GMT 2021) ----- Confirming a Wide-Separation Directly-Imaged Infant Planet around a Young, Dusty Star Clone from Phase 1: This 8-orbit mid-cycle proposal requests HST/STIS coronagraphic imaging to confirm a candidate wide-separation protoplanet seen around AB Aur. Near infrared data sets obtained over multiple epochs but only fully analyzed in May 2020 suggest a protoplanet whose colors/spectrum are distinguishable from scattered starlight and whose astrometry hints at orbital motion. Optical imaging roughly contemporaneous with recently scheduled ground-based extreme AO follow-up observations in Fall 2020/Winter 2021 are required. Only optical imaging can conclusively rule out the alternate hypothesis: that this signal is a static disk feature. STIS is the only suitable optical high-contrast imaging instrument: its ability to yield unbiased detections of disks and point sources is unmatched by any ground or space-based facility. The analysis will decisively point to one of 3 interpretations: 1) thermal emission from a protoplanet formed by disk instability, 2) an orbiting disk region heated and puffed up by an unseen planet, or 3) a non-rotating disk feature whose pathological colors and near-IR variability can be mistaken for an orbiting protoplanet. Our STIS imaging multi-roll reference star differential imaging will easily achieve the required contrast to distinguish these scenarios. If interpretations 1) or 2) are supported, this candidate would be HST's first bona fide exoplanet direct imaging discovery, given the recent controversy over Fomalhaut b. Moreover, if 1) is correct, the program rewrites the field's understanding of planet formation, decisively demonstrating the existence of multiple mechanisms for forming jovian planets: core accretion AND disk instability. ***Critical Scheduling Note *** Note to PC/CS: Due to the geometrical (orientation) restrictions for these observations, the only suitable orientation windows are very quickly approaching, and we really need to know ASAP how that can fit into the existing or soon to be built LRP (long range plan) and conform for those specific orient-constrained dates that guide stars are available. ----- ***Overall Description*** **Visit-Set Organization** -- Our program consists of TWO Visit-Sets of 4 orbits each (for a total of 8 orbits in the entire program). The 4 orbits within a single Visit-Set consist of THREE target visits and ONE interleaved PSF Calibrator visit. The 4 orbits within a single Visit-Set must be continuous. However, the two Visit-Sets need not be continuous with one another (i.e. Visit-Set #2 can happen months after Visit-Set #1). **Aperture (Placement of the star in each observation)** -- After target acquisition, the star should be nominally placed at the "Bar10/Lower-Left occulter position, IWA=0.270" " offset from (hereafter, Bar10/LL). Bar10/LL is defined in Table 3 of Schneider et al. (2017, Instrument Science Report 2017-03). Quantitatively, Bar10/LL is equal to the original Bar10 Reference Position PLUS an additional "Pos Targ" offset of [-1.20088",-1.27353"]. Around this "nominal" Bar10/LL position, our exposures consist of a 3-point dither pattern: nominal ("center"), +1/4th pixel, -1/4th pixel as labeled in the "Sequences" for each orbit. **ORIENT constraints** -- For Visit-Set 1, we define an ABSOLUTE ORIENT constraint for the first orbit (Set1-ORBIT 1) of 110-140 deg and a RELATIVE ORIENT constraint for other target orbits in Visit-Set 1 of: +4 degrees (Set1-Orbit 2) and +6 to +10 degrees (Set1-Orbit 4). For Visit-Set 2, we define an ABSOLUTE ORIENT constraint for the first orbit (Set2-ORBIT 1) of 30-70 deg and a RELATIVE ORIENT constraint for other target orbits in Visit-Set 2 of: -4 degrees (Set2-Orbit 2) and -6 to -10 degrees (Set2-Orbit 4). **Strategy/Rationale for Bar10/LL position and ORIENT constraints** -- Our observations must leave unobscured a region between rho = 0.4" and 0.7" at a sky position angle of ~180 degrees (i.e. nearly due-south on the sky). We hereafter refer to this region as the 'region of interest' or "ROI". This means the ROI must not be blocked by occulters nor obscured by the diffraction spikes. We define "obscured by diffraction spikes" as being within 20 deg of the angles 45, 135, 225, and 315 on the detector. Bar10/LL can allow access to a >180 deg region exterior to 0.27". The ABSOLUTE ORIENT angle ranges for Visit-Set 1, Orbit 1 and Visit-Set 2, Orbit 1 allow the ROI to be 1. free from occulter obscuration and 2. free from diffraction spike obscuration. The RELATIVE ORIENTS for subsequent Orbits in each Visit-Set likewise allow the ROI to be 1. free from occulter obscuration and 2. free from diffraction spike obscuration. In the above paragraph and absolutely critical to the success of our program is the assumption that northPA= ORIENT-45, where positive northPA values increase as true north moves *clockwise* from the detector +Y axis. Thus, for example, ORIENT=135 means northPA=90 deg: the true-north direction would lie along a perfectly horizontal line to the right from BAR10/LL. Our ROI would lie exactly to the left of BAR10/LL occulter position: with the same y-coordinate on the detector but a smaller x-coordinate value (by ~11.8 pixels). Our CS at STScI for this program has verified that this understanding of the STIS coordinate system is the correct one. Note to PC/CS: we would like confirmation that again we have the above understanding about the STIS northPA correct and that our ORIENT constrainsts coupled with the BAR10/LL position is would in fact leave our ROI free from obscuration by the occulter and diffraction spikes. **Expected Visibility window** - APT tells us that we have the following approximate visibility windows. For VISIT-SET1: Dec 7-16 2020; Jan 2-5, 8-11 2021; For VISIT-SET2: Feb 7-Mar 6 2021 (with a few breaks). ---------------- ***Preferences/Clarifications*** **RELATIVE ORIENTS** - For both VISIT-SETS we have an absolute ORIENT constraint and then RELATIVE ORIENT constraints with some ranges. Where scheduling flexibility is allowed, we prefer to MAXIMIZE the RELATIVE ORIENTS in each VISIT-SET. For instance, for VISIT-SET1, ORIENTS of 110 (orbit 1), 114 (orbit 2), and 120 (orbit 4) [i.e. +4 and +10 relative angle offsets] is PREFERABLE to ORIENTS of 110 (orbit 1), 114 (orbit 2), and 116 (orbit 4) [i.e. +4 and +6 relative angle offsets]. ---- ***Other Notes*** Note to PC/CS: Commensurate with our use of the BAR10 occulter (POS TARGed to the LL corner) we need to recenter and appropriately size for our target region the readout subarray to be used. Thus we invoke the "AVAILABLE" mode parameters CENTERAXIS2 and SIZEAXIS2 set appropriately. We have set the proposal mode to "AVAILABLE" to turn off APTs otherwise spurious and prolific warnings of improper placed subarrays in SUPPORTED mode. We understand implementation of AVAILABLE mode requires the concurrence of our PC, which we request to be approved here. Note that this combination of parameters has been routinely used with the BAR5/10 aperture since it was added to those known by APT (e.g., GO proposals 13786, 15219, 16205, etc.) to specify the detector-based readout area. NOTE TO PC: These observations require Two-FGS fine-lock guiding. T. Currie is an acknowledged leader in the field of high-contrast imaging with extensive expertise in subjects critical to this proposal: PSF subtraction methods, forward-modeling of planets and disks, and precise spectral extraction. He has built advanced pipelines that have been used in peer-reviewed papers for numerous instruments, including SCExAO/CHARIS [which motivates this program and will be utilized for ground-based follow-up]. He has published extensively on systems similar to AB Aur, including results finding evidence for candidate planets (HD 100546) and ones refuting previous claimed detections (LkCa 15), and has published on HST coronagraphic high-contrast imaging of planetary systems (Currie et al. 2012, 2012; Kenyon et al. 2014). G. Schneider is a veteran user and acknowledged expert in STIS coronagraphic imaging and arguably *the* point-person behind the multi-roll + RDI observing strategy described in this proposal. He provided critical analysis to an earlier, complementary HST data set which partially motivates this proposal. C. Grady and J. Wisniewski are veteran users and acknowledged experts in STIS coronagraphy. T. Muto, R. Dong, and W. Lyra are leading planet formation theorists with extensive publications on interpreting scattered light images of protoplanetary disks and signatures of embedded planets. O. Guyon and J. Lozi are acknowledged leading experts in ground-based high-contrast imaging and members of the SCExAO team. SCExAO will be used for complementary ground-based follow-up of our target. M.
