PDS 70 is currently the only known system where giant planet formation can be witnessed and studied directly. With this program we propose to obtained the deepest images ever obtained of this system, with the same spatial resolution as ground-based 8-m telescope in the near-infrared. With these optical images showing light scattered by submicron particles that follow gas drag in the system, we will study 1/ gas accretion by the forming protoplanets carving the cavity, and 2/ the extended structure of the disk beyond 80au that has never been resolved from the ground. GO 16305: 0/ EXECUTIVE SUMMARY This is a 16-orbit program to obtain deep STIS coronagraphic images of the PDS 70 systems, which hosts a young K7 star, a protoplanetary disk, and two giant planets imaged with ground based telescopes. Along with the Science target( PDS 70), we will also observe a PSF target (UCAC4-203-088985). This second target is a calibration target used to subtract the PSF in the science exposures during data processing and allow the observation of the fainter circumstellar objects. We will obtain 12 orbits on the science target at 6 different orientations of the spacecraft to obtain a full 360D unobstructed view of the disk down to the smallest separations possible to the star. We will also obtain 4 orbits on the PSF target to allow starlight subtraction. Each orbit combines short exposures on the BAR5 mask to reach the sensitivty required to analyse the nearby circumstellar disk, then a longer exposure on the wider WEDGEA1.0 position to observe possible fainter material at larger separation. ----------------------------- 1/ VISIT STRUCTURE AND LINKAGE: We will obtain observations on the science target PDS 70 at 6 different telescope orientations (rolls), interleaved with contemporaneous PSF star observations (timing constaints). To facilitate the scheduling of the observations with both timing and orient constraints, we split the 16 orbits in four sets of 4 orbits. For clarity, we number the visits with the first digit referencing the index of the set (1* to 4*), and the second digit referencing the orbit number within the set (*1 to *4). The visit structure is the same for the four sets: On set has 3 visits to the science target at 3 different orientations, and one interleaved visit to the PSF target. The visit to the PSF target always comes after two visits to the science target and before the third science visit of the set, and is thus always numbered *3 (so visits 13, 23, 33, 43 are the visits to the PSF target). The four visits within one set must be executed in back to back orbits (Timing Requirements: "AFTER VISIT #(n-1) BY 0.5 orbits to 1.5 orbits"). There is no timing requirement between the four sets and can be executed separately (however the have relative orient constraints, see next section). 2/ORIENTATION CONSTRAINTS: The visits to the PSF target (numbers *3) don't have any orient constraints. The visits to the science target all have relative orient constraints between them, but no absolute orient constraint. Within each set: We define the second visit to the science target (number *2) as the reference orient. The two other science visits have relative orient constraints form this reference orient #*2: - ORIENT FROM this reference orient (#*2) BY -30D to -20D for the first science visit (#*1), - ORIENT FROM this reference orient (#*2) BY +30D to +20D for the 3rd science visit (#*4). We provide a 10D range to ease scheduling, but have a preference for larger roll angles (-30D and +30D) over smaller ones (-20D and +20D). Between the four sets: We define the reference orient of the first set (visit #12) as reference orient for the three other sets, and we put relative orient constraints for visits #22, #32, and #42 from this visit. The first two sets must have similar orientations: for visit #22, we put ORIENT FROM #12 BY -2D to +2D. The 3rd set must have a +100D or -100D roll angle from the two first sets: for visit #32, we put ORIENT FROM #12 BY 98 to 102D. We don't have to possibility to add the -100D option: we equally accept ORIENT FROM #12 BY -102D to -98D. The 4rth set mus have a similar orientation as the 3rd set: for visit #42, we put ORIENT FROM #12 BY 98 to 102D. As for visit #32, we equally accept ORIENT FROM #12 BY -102D to -98D. The tolerence of 4D may be somewhat relaxed if scheduling is difficult. 3/ GUIDE STARS: We require pointing and roll control with 2-FGS guiding. Single-FGS guiding does not offer sufficient target position stability for coronagraphy. 4/ EXPOSURE LAYOUT WITHIN AN ORBIT: All 16 orbits have the same exposure structure: - after the guide stars acquisition, each orbits begins with a TARGET ACQ exposure, used to precisely position the target behind the coronagraphic masks; We use the F25ND3 for all target ACQ exposures. - The target is the moved to the BAR5 coronagraph position, and a short exposure is obtained with CR-SPLIT=2. - The target is then moved to the WEDGEA1.0 position, and a long exposure filling the rest of the visibility period is acquired. 5/ EXPOSURE TIMES All coronagraphic exposures use GAIN=4. For the TARGET ACQ, the exposure time is computed with the target acquisition ETC to have SNR ~100. The BAR5 exposure times are computed to reach ~80% of the full-well capacity just outside the mask (assuming a 1.9e-3 starlight attenuation at the edge of the mask) for each CR-SPLIT acquisition. The total exposure time and number of CR-SPLIT on the science target is defined to reach a 5sigma contrast limit of 5e-4 after 2x2 pixel binning on the disk for each roll. The number of BAR5 exposures for the PSF target is set to mimic those on the science target. The WEDGEA1.0 exposure times are simply set to fill up the rest of the orbits. We simply ensure that the longer exposure don't saturate (saturation limit at the edge of WEDGEA1.0 is 5100s for PDS70, and 4700s for the PSF star). 6/ SUBARRAYS We use Subarrays for all coronagraphic exposures to minimise the readout time and gain on exposure time. All subarrays must be centered on the selected aperture. For the BAR5 exposures, we use SIZEAXIS2=140 to have a field of view of about 7''. For the WEDGEA1.0 exposures, we use SIZEAXIS2=427, giving a large field of view of about 21''. 7/ REFERENCE STAR NOTE: this target was changed from phase 1 to allow a better calibration of the science exposures and have a better schedulability with the science target PDS 70. We selected out reference star to have the best color match and V magnitude match as our science target. Our PSF star matches the B-V color of PDS70 by 0.02mag (B and V magnitudes from UCAC4 catalog, Zacharias+2012), and its V-I color by 0.01mag (V and I magnitudes from the ROSAT catalog, Kigara+2012). Its V magnitude matches the science target V magnitude by 0.1mag. It is 11D away from PDS70. 8/ REDUCED GYRO OPERATIONS In the eventuallity of reduced gyro operations, we anticipate difficulties to schedule our observations and satisfy our orient constraints, as well as an increased jitter. The increased jitter may lower the sensitivity of our observations but should not prevent the main scientific outcome. The scheduling difficulties may be more problematic and may require discussions with the PC to decide mitigation scenarios.

Clear view X axis: -55pix -- +969pix Clear view Y axis: -70pix -- +70pix We changed the Wedge position from WEDGEA0.6 described in the proposal to WEDGEA1.0 to allow for a larger field-of-view, albeit a slightly larger inner working angle. The 80% Full well capacity is Tint = 5173s, computed from the stellar flux at the brightest pixel and a raw contrast of 2e-4 just at the edge of WEDGEA1.0. Given that the time before occultation is shorter than this saturation limit, we simply fill the orbit with one long exposure for the remaining visibility. We set SIZEAXIS2 to the maximum size allowed by the detector size given the A1.0 position on the detector.

This is the 2nd PDS70 visit in the fourth set. The four visits within each set must be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: This visit must have a relative ORIENT of 100D (+/-2D) FROM visit #12 (reference orient from the first set). It can equally have an ORIENT FROM visit #12 by -100D instead of +100D, although APT doesn't allow this option. We have no preference between the two options. The two other visits to PDS70 in the 4th set (#41 and #44) carry relative orientation constraints with respect to this visit. Relative Timing: This visit (#42) should immediately preceed visit #43 and should immediately follow Visit #41 (back-to-back orbits).

This is the PSF visit in the fourth set. The four visits within each set must be executed sequentally in contiguous orbits interrupted only for Earth occultation. Orientation: We set no orient constraint on the PSF orientations. However, as we selected the PSF target to be near the science target and given the sequential orbit sequence, we expect to have an absolute orientation very similar to visit #42 within a few degrees. This is important so we maintain similar Sun and Beta angles for the science target and its PSF calibrator. Relative Timing: This visit (#43) should immediately preceed visit #44 and should immediately follow Visit #42 (back-to-back orbits).
