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…
Evidence of a Decreased Binary Fraction for Massive Stars Within 20 Milliparsecs of the Supermassive Black Hole at the Galactic Center
Devin S. Chu, Tuan Do, Andrea Ghez +12
We present the results of the first systematic search for spectroscopic binaries within the central 2 x 3 arcsec around the supermassive black hole at the center of the Milky W…
Stellar Populations in the Central 0.5 pc of Our Galaxy III: The Dynamical Sub-structures
Siyao Jia, Ningyuan Xu, Jessica R. Lu +12
We measure the 3D kinematic structures of the young stars within the central 0.5 parsec of our Galactic Center using the 10 m telescopes of the W.~M.~Keck Observatory over a time s…
The Swansong of the Galactic Center Source X7: An Extreme Example of Tidal Evolution near the Supermassive Black Hole
Anna Ciurlo, Randall D. Campbell, Mark R. Morris +14
We present two decades of new high-angular-resolution near-infrared data from the W. M. Keck Observatory that reveal extreme evolution in X7, an elongated dust and gas feature, pre…
The Star Formation History of the Milky Way's Nuclear Star Cluster
Zhuo Chen, Tuan Do, Andrea M. Ghez +6
We report the first star formation history study of the Milky Way's nuclear star cluster (NSC) that includes observational constraints from a large sample of stellar metallicity me…
Measuring the alpha-abundance of subsolar-metallicity stars in the Milky Way's central half-parsec: testing globular cluster and dwarf galaxy infall scenarios
Rory O. Bentley, Tuan Do, Wolfgang Kerzendorf +4
While the Milky Way Nuclear star cluster has been studied extensively, how it formed is uncertain. Studies have shown it contains a solar and supersolar metallicity population that…
