The Proper Motion of Draco II with HST using Multiple Reference Frames and Methodologies

Jack T. Warfield, Kevin A. McKinnon, Sangmo Tony Sohn +13

We present proper motion (PM) measurements for Draco II, an ultra-faint dwarf satellite of the Milky Way. These PMs are measured using two epochs of Hubble Space Telescope Advanced…

The Orbits of Isolated Dwarfs in the Local Group from New 3D Kinematics: Constraints on First Infall, Backsplash, and Quenching Mechanisms

Paul Bennet, Ekta Patel, Sangmo Tony Sohn +8

It is commonly supposed that quenched field dwarfs near the edge of the Local Group (LG) are backsplash galaxies, having previously orbited within the Milky Way (MW) or M31's viria…

JWST-TST DREAMS: NIRSpec/PRISM Transmission Spectroscopy of the Habitable Zone Planet TRAPPIST-1 e

Néstor Espinoza, Natalie H. Allen, Ana Glidden +32

TRAPPIST-1 e is one of the very few rocky exoplanets that is both amenable to atmospheric characterization and that resides in the habitable zone of its star -- located at a distan…

HSTPROMO Internal Proper Motion Kinematics of Dwarf Spheroidal Galaxies: II. Velocity Anisotropy and Dark Matter Cusp Slope of Sculptor

Eduardo Vitral, Roeland P. van der Marel, Sangmo Tony Sohn +8

We analyze three epochs of HST imaging over 20 years for the Sculptor dwarf spheroidal galaxy, measuring precise proper motions for 119 stars and combining them with 1760 existing…

The HST Legacy Archival Uniform Reduction of Local Group Imaging (LAURELIN). I. Photometry and Star Formation Histories for 36 Ultra-faint Dwarf Galaxies

Meredith J. Durbin, Yumi Choi, Alessandro Savino +14

We present uniformly measured resolved stellar photometry and star formation histories (SFHs) for 36 nearby ( 400 kpc) ultra-faint dwarf galaxies (UFDs; $-7.1 \le M_V \le…

The Hubble Space Telescope Survey of M31 Satellite Galaxies IV. Survey Overview and Lifetime Star Formation Histories

A. Savino, D. R. Weisz, A. E. Dolphin +35

From orbits of HST imaging, we present deep homogeneous resolved star color-magnitude diagrams that reach the oldest main sequence turnoff and uniformly measured star forma…
