A Kinematic Study of Wolf-Rayet Stars at the Galactic Center I: Binary Candidates and Constraints on the Binary Fraction
Rory O. Bentley, Tuan Do, Andrea Ghez +13
We report the binary fraction of Wolf-Rayet (WR) stars within 0.5~pc of the Galactic center obtained through the longest time-baseline (1994-2024) kinematic study of this populatio…
IRS 9: The Case for a Dynamically-Ejected Star from the Galactic Center
Matthew Hosek, Tuan Do, Smadar Naoz +7
Measuring stellar motions at the Milky Way's Galactic center (GC) provides unique insight into the dynamical processes within galactic nuclei. We present proper motion measurements…
The HST-Gaia Near-Infrared Astrometric Reference Frame near the Milky Way Galactic Center
Matthew W. Hosek, Tuan Do, Gregory D. Martinez +5
We present the first high-precision proper motion catalog, tied to the International Celestial Reference System (ICRS), of infrared astrometric reference stars within R 25"…
New Evidence for a Flux-independent Spectral Index of Sgr A* in the Near-infrared
Hadrien Paugnat, Tuan Do, Abhimat K. Gautam +11
In this work, we measure the spectral index of Sagittarius A* (Sgr A*) between the (1.6 m) and (2.2 m) broadband filters in the near-infrared (NIR), sampling o…
Orbital and Atmospheric Characterization of the 1RXS J034231.8+121622 System Using High-Resolution Spectroscopy Confirms That The Companion is a Low-Mass Star
Clarissa R. Do Ó, Ben Sappey, Quinn M. Konopacky +33
The 1RXS J034231.8+121622 system consists of an M dwarf primary and a directly imaged low-mass stellar companion. We use high resolution spectroscopic data from Keck/KPIC to estima…
