Wolff University of Arizona N ------------------------------------------------------------------------------------ Abstract The remarkable breadth of exoplanetary systems most likely finds its origin in their parent protoplanetary disks. Understanding the diversity of the physical properties and evolutionary pathways of these disks is therefore key to interpret the wealth of data that has been accumulated on exoplanets over the past two decades. High-angular resolution observations of disks, the most direct method to characterize their properties, is a challenging task in most cases and detailed individual studies are limited to a small set of favorable objects which are unlikely to be representative of the entire population. Edge-on protoplanetary disks offer unique advantages by blocking direct starlight and by providing an ideal perspective to study the disk vertical structure, which is expected to be affected by dust settling as part of the planet formation process. After a few serendipitous early discoveries, a method to identify likely edge-on disks was designed based on their peculiar spectral energy distribution. An HST pilot program confirmed that over half of the candidates were resolved as edge-on disks. Here we propose to conduct a complete survey of all HST-accessible edge-on disk candidates in four nearby star-forming regions (Taurus-Auriga, Chamaeleon, Lupus, Ophiuchus) to confirm their nature, and to enable a statistically meaningful ensemble analysis of the properties of protoplanetary disks. This survey is expected to roughly triple the number of edge-on disks identified through a uniform set of criteria in these regions and will allow us to empirically determine the true diversity of disk properties and to identify trends connected to disk evolution. ------------------------------------------------------------------------------------ Observations Description ------------------------ The program aims at imaging objects that are candidate edge-on protoplanetary disks based on SED selection criteria that our group has tailored based on known samples of such objects. We selected the 29 highest priority targets in four nearby star-forming regions (Taurus, Ophiuchus, Lupus, Chamaeleon) that have not yet been observed with HST and cannot be observed with ground-based adaptive optics. To achieve the highest spatial resolution, the primary mode of observation is WFC3/UVIS with the F606W filter, combined with a shorter F814W observation to obtain color information and distangle jet emission from scattered light off the disk. Due primarily to foreground extinction, some 17067( 9) - 08-May-2023 15:34:08 - [ 2] objects are too red for this strategy to be effective. Instead, we adopt either 1) a single F814W observation (2 targets), or 2) a WFC3/IR F160W observation (13 targets). In the latter case, we adopt the F610W filter instead of the F110W filter to avoid the worst undersampling of the camera at the shorter wavelength. Furthermore, because the sources are located in molecular clouds, they are often rather isolated and single guide star acquisition is preferred/necessary. The loss of performance in terms of roll drift is acdeptable given the individual integration times and the fact that WFC3 is essentially on-axis. In all cases, exposures are split using CR-SPLIT=2 or CR-SPLIT=3 for cosmic ray rejection. We prefer this to dithering in order to preserve the sharpest images, with easier to model PSF. The interesting objects are extended and thus the finer PSF samlpign enabled by dithering is not necessary for the analysis. The only APT warnings are about: 1) the relatively short integration times with the F814W filter, which could lead to non-negligible CTE. In our experience, this does not affect the quality of edge-on disk images and thus we opted to not use the FLASH option. 2) single guide star acquisition setup for the 2-filter UVIS sequences (14 such objects). We are not sure why this is since for single-filter UVIS and IR sequences, this is not an issue. Suggestions are welcome if the requested setup is suboptimal. ------------------------------------------------------------------------------------ 17067( 9) - 08-May-2023 15:34:08 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 2 SSTTAUJ04153 STAR, PRE-MAIN SEQUENCE RA=04H15M35.6000S, J2000 R=19.6, I=15.8 5.6+284741 STAR, PROTOPLANETARY DEC=+28D47'41.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 3 SSTTAUJ04181 STAR, PRE-MAIN SEQUENCE RA=04H18M10.5000S, J2000 R=18.9, I=16.6 0.5+284447 STAR, PROTOPLANETARY DEC=+28D44'47.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 5 SSTTAUJ04273 STAR, PRE-MAIN SEQUENCE RA=04H27M30.2000S, J2000 R=17.9, I=16.2 0.2+244123 STAR, PROTOPLANETARY DEC=+24D41'23.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 7 SSTTAUJ04364 STAR, PRE-MAIN SEQUENCE RA=04H36M42.0000S, J2000 I=20.0 2.0+265339 STAR, PROTOPLANETARY DEC=+26D53'39.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 10 SSTGBSJ11072 STAR, PRE-MAIN SEQUENCE RA=11H07M21.4000S, J2000 H=12.4 1.4-772211 STAR, PROTOPLANETARY DEC=-77D22'11.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 11 SSTGBSJ11095 STAR, PRE-MAIN SEQUENCE RA=11H09M52.5000S, J2000 R=19.5, I=18.2 2.5-774035 STAR, PROTOPLANETARY DEC=-77D40'35.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 12 SSTGBSJ11100 STAR, PRE-MAIN SEQUENCE RA=11H10M3.4000S, J2000 H=14.9 3.4-763311 STAR, PROTOPLANETARY DEC=-76D33'11.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 13 SSTGBSJ11105 STAR, PRE-MAIN SEQUENCE RA=11H10M53.6000S, J2000 R=20.0, I=17.5 3.6-772500 STAR, PROTOPLANETARY DEC=-77D25'0.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 14 SSTGBSJ13052 STAR, PRE-MAIN SEQUENCE RA=13H05M21.7000S, J2000 R=17.0 I=16.5 1.7-773809 STAR, PROTOPLANETARY DEC=-77D38'9.00" DISK, T TAURI STAR Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 18 SSTC2DJ16102 STAR, PRE-MAIN SEQUENCE RA=16H10M27.4000S, J2000 I=19.5 7.4-390230 STAR, PROTOPLANETARY DEC=-39D02'30.00" DISK, T TAURI STAR Reference Frame: ICRS 17067( 9) -
