An Estimate of the Binary Star Fraction Among Young Stars at the Galactic Center: Possible Evidence of a Radial Dependence

Abhimat K. Gautam, Tuan Do, Andrea M. Ghez +8

We present the first estimate of the intrinsic binary fraction of young stars across the central 0.4 pc surrounding the supermassive black hole (SMBH) at the Milky Way Ga…

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…

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…

The double galaxy cluster Abell 2465 - II. Star formation in the cluster

Gary A. Wegner, Devin S. Chu, Ho Seong Hwang

We investigate the star formation rate and its location in the major merger cluster Abell 2465 at = 0.245. Optical properties of the cluster are described in Paper I. Measureme…
