Gaia can only detect the brightest stars in star forming regions at the distance of M31, so HST is the only observatory currently capable of measuring PMs of M31 satellite dwarf spheroidals. We propose to obtain second epoch imaging of 7 M31 satellites (And I, II, III, VII, XV, XVI, XXVIII), targeting the same fields with earlier deep HST observations to measure PMs with uncertainties of 40-50 km/s. We will use the PM-based 6D phase space information of satellites to constrain the total M31 mass with uncertainties at the 30% level. We will also test the dynamical stability of the Great Plane of Andromeda using our PM results for And I, III, and XVI. This will provide clues to the origin of satellite planes observed around M31 as well as the MW. The orbits derived for individual satellites will allow us to disentangle the processes that have contributed to the quenching of star formation, connect our target galaxies to M31 tidal structures, and test the merger scenario of And II. Altogether, our proposed measurements will nearly triple the sample of M31 satellites with available PMs, dramatically improving our understanding of the M31 halo and its satellite system. A revised estimate for the mass of M31 will also improve our understanding of the dynamics in the Local Group (LG), and set an important benchmark for studies of satellite systems beyond the LG. Finally, the results from this program will inform us how representative the MW is in a cosmological context.We will observe 7 dwarf satellite galaxies of M31 using ACS/WFC and WFC3/UVIS. All of our target galaxies have deep ACS/WFC imaging data in the HST archive. All but And VII also have deep WFC3/UVIS imaging data observed as parallel fields. The dwarf galaxies And I, II, III, XV, XVI, and XXVIII were observed in 2013-2015 through HST programs GO-13028 and GO-13739 using the F475W and F814W filters. And VII was observed in 2006 through HST GO-10430 using the F435W and F555W filters.
In this program, Each target dwarf galaxy will be observed using the same telescope pointings and orientations as the first-epoch images to maximize the overlaps of both primary ACS/WFC and parallel WFC3/UVIS fields between the first- and second-epoch data. This will also minimize errors originating from imperfect CTE and geometric distortion corrections. To measure PMs, it is sufficient to observe only in one filter. We will image all target galaxies, with the exception of And VII, using the F814W filter to measure PMs. F814W is found to give one of the best astrometric handles on background galaxies. For And VII, we will use the F606W filter which has a wider bandwidth than the F555W originally used in the first epoch, for creating high signal- to-noise (S/N) templates for background galaxies, i.e., unlike the other galaxies, we will use the second-epoch data to build templates for And VII. Individual exposure times will be half-orbit long, and we will use dithered patterns specially designed to maximize pixel-phase coverage.The majority of the investigators are members of the HSTPROMO group, led by co-I van der Marel, which has published numerous papers reporting proper motion measurements of dwarf galaxies, globular clusters, individual stars along stellar streams, and distant Milky Way (MW) halo stars.[*] PI Sohn has led many HST programs over the past decade for measuring proper motions of M31, dwarf spheroidal galaxies in the Milky Way halo (Leo I, Draco, and Sculptor), stars along stellar streams such as Sagittarius, Orphans, and Lethe, distant Milky Way globular clusters, and NGC 147 and 185. He has been the PI for several of these programs, and will oversee this entire program. Co-PI Fardal is an expert in dynamical analysis of stellar streams and galaxies in the Local Group. He will oversee the theoretical component of this program. Co-Is Besla, Patel, and van der Marel are experts in dynamical analysis of Local Group galaxies. CoI Kallivaylil is a expert in HST astrometry and proper motions, and is PI of the HST Treasury program of MW satellites. CoI Pawlowski is an expert on the topic of satellite galaxy phase-space correlations, in particular, planes of satellites and their use to predict proper motions, as well as the comparison of satellites systems and their orbits with numerical simulations to test cosmological models. CoI del Pino Molina is an expert in analysis of internal dynamics of galaxies in the Local Group. CoI Tollerud is an expert in observations of the internal dynamics of M31 satellites and techniques for connecting observations of the M31 system to simulations. CoI Watkins is an expert in velocity anisotropy analysis and dynamical mass estimation, and has particularly published papers studying the M31 galaxy and its satellites. CoI Weisz is an expert on observations of resolved stellar populations with HST, star formation histories, and the formation and evolution of dwarf galaxies. CoI Wetzel is an expert in cosmological simulations and has developed a framework to use them to model orbital histories of individual satellites based on the observed parameters. CoI Samuel is a graduate student working under the supervision of CoI Wetzel to understand how the dynamics of satellite dwarf galaxies impact their formation history.

This visit spends 4 orbits in total with ACS/WFC being the primary and the WFC3/UVIS being the parallel instruments. For proper motion measuring purpose, we require to match our telescope orientations to the first-epoch observations for both the primary and parallel fields. We have accordingly added the Visit Orientation Requirements. We have grouped Visits 01, 02, and 03 and specified these visits to be observed within a 15 day period so that all images can be treated as a single-epoch data for astrometric analyses. Our science requires that the time baseline between the previous first- and this cycle's second-epoch is at least 6 years apart (this is specified in the Phase 1 proposal). We therefore added a Timing Requirement of "AFTER 01-JAN-2021:00:00:00".(Tic-Visit

This visit spends 4 orbits in total with ACS/WFC being the primary and the WFC3/UVIS being the parallel instruments. For proper motion measuring purpose, we required to match our telescope orientations to the first-epoch observations. We have accordingly added the Visit Orientation Requirements.(Tic-Visit
