0 Assigned ID: 3548 ----- Attempting Submission 1 (Fri Mar 25 21:01:15 GMT 2022) ----- Scheduling requirements for each target are optimally chosen to enhance data quality. If the scheduling requirements are too tight, I am happy to work with schedulers to allow for more available times. Edit on 09/22/22: Each visit now is contained within a non-interruptable sequence, as requested. All visits have changed slightly due to changes in orbital visibility by selecting "no gyro bias update". Edit 09/23/22: Visit 5 has been changed to allow for schedulability from Oct 15-17. Edit 09/23/22: I've altered the "between" window for Oct 15-17 to Oct 16 00:00 -- Oct 17 00:00 to avoid bright field stars at Linda's suggestion. Edit 10/28/22: I've removed the BETWEENs up to and including 15-NOV-2022 -- 17-NOV-2022 upon Linda's suggestion. Edit: 11/04/22: Again modifying BETWEENs for bright object avoidance. Edit 11/07/22: Fixing mistake on BETWEENs. Edit 11/08/22: Changed apertures for one exposure in visit 3 and 4. Selected apertures are now correct for all visits. Edit 01/13/23: Added new BETWEENs to prevent overlap with bright objects. Removed an old BETWEEN that overlapped the new ones. Relaxed scheduling requirements on Visit 04 to allow for better scheduling availability. Edit 02/17/23: Added visit 09 to repeat the failed visit 03. Updated scheduling for visit 04 to account for this. Edit 10/06/23: Changed BETWEENs for Visit 07 to avoid bright field stars. Altered BETWEENs for Visit 02 for better schedulability, as discussed. Edit 10/31/23: Changed BETWEENs for visit 04 to avoid stars in the field. Edit 01/18/24: Added Visits 10 and 11 per HOPR 92714 and 92717. Edit 0726/24: Edit to BETWEENs for Visit 10 and 11 for BO avoidance. -1925174641 ----- Attempting Submission 1 (Wed Jul 13 20:08:06 GMT 2022) ----- ----- Attempting Submission 2 (Thu Sep 22 15:57:38 GMT 2022) ----- HST Phase II Proposal 17206 successfully submitted.

One of the most favored planetary formation models is the streaming instability, which predicts that binaries should be extremely common, especially among the Cold Classical. It also predicts that the spins of individual binary components will be well aligned with the binary orbit. Unfortunately, to date, this prediction has been difficult to test, but with increasingly long observational baselines, non-Keplerian orbital analysis is able to precisely measure both the shapes and spin poles of individual binary components. With these measurements, a quantitative test of the streaming instability model of planetesimal formation can be completed. In this program, we request 8 orbits to precisely measure the spin poles and shapes of Cold Classical TNOs, which will enable a detailed test of planet formation models. Observations of tranneptunian binaries to provide precise constraints on non-Keplerian motion in the binary mutual orbit, allowing for precise determination of shape and spin properties. Using preliminary models with the already existing orbital data, we are able to predict optimal times for observing, optimizing both the "information gained" by each observation and the binary separation. We propose a total of 8 single-orbit visits using WFC3/UVIS in standard imaging mode, using a 512x512 subarray to optimize exposure times, and a dither pattern to optimally sample the PSF, as is common for imaging TNO binaries. We choose the F350LP filter to maximize the signal from our target with at least 4 exposures per visit, allowing us to achieve the best data quality possible. This maximizes astrometric precision, the goal of these observations. PI Proudfoot is a graduate student that has expertise in all areas of this proposal. He is an expert in non-Keplerian orbit fitting and HST image analysis. He is one of the main developers of MultiMoon, the non-Keplerian orbit fitting tool that forms much of the core of this proposal. He is also the developer of the PSF fitting tools that will be extensively used for this project. In addition, he is an expert in Bayesian parameter inference, spin-orbit dynamics of TNOs, and planet formation. Co-I Ragozzine is PI Proudfoot's graduate faculty advisor. He is also an expert in TNB orbit fitting, with extensive experience in detecting non-Keplerian effects caused by massive moons (like those of Haumea). He has been PI of multiple HST programs focusing on understanding the formation, evolution, and physical characteristics of TNOs. Co-I Grundy is a major expert in HST data reduction and analysis for TNBs. He has led several programs focusing on characterization of individual TNB systems. He maintains an extensive online catalog of TNBs. Co-I Spencer is an undergraduate student member of Co-I Ragozzine's group.
