J01020100-7122208: an accreted evolved blue straggler that wasn't ejected from a supermassive black hole
D. Brito-Silva, P. Jofré, D. Bourbert +3
J01020100-7122208 is a star whose origin and nature still challenges us. It was first believed to be a yellow super giant ejected from the Small Magellanic Cloud, but it was more r…
The COMBS Survey -- III. The Chemodynamical Origins of Metal-Poor Bulge Stars
Madeline Lucey, Keith Hawkins, Melissa Ness +6
The characteristics of the stellar populations in the Galactic Bulge inform and constrain the Milky Way's formation and evolution. The metal-poor population is particularly importa…
Distant Relatives: The Chemical Homogeneity of Comoving Pairs Identified in Gaia
Tyler Nelson, Yuan-Sen Ting, Keith Hawkins +3
Comoving pairs, even at the separations of AU, are a predicted reservoir of conatal stars. We present detailed chemical abundances of 62 stars in 31 comoving p…
The Stars of the HETDEX Survey. I. Radial Velocities and Metal-Poor Stars from Low-Resolution Stellar Spectra
Keith Hawkins, Greg Zeimann, Chris Sneden +18
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is an unbiased, massively multiplexed spectroscopic survey, designed to measure the expansion history of the universe thr…
TESS Hunt for Young and Maturing Exoplanets (THYME) V: A Sub-Neptune Transiting a Young Star in a Newly Discovered 250 Myr Association
Benjamin M. Tofflemire, Aaron C. Rizzuto, Elisabeth R. Newton +27
The detection and characterization of young planetary systems offers a direct path to study the processes that shape planet evolution. We report on the discovery of a sub-Neptune-s…
TESS Hunt for Young and Maturing Exoplanets (THYME) IV: Three small planets orbiting a 120 Myr-old star in the Pisces--Eridanus stream
Elisabeth R. Newton, Andrew W. Mann, Adam L. Kraus +50
Young exoplanets can offer insight into the evolution of planetary atmospheres, compositions, and architectures. We present the discovery of the young planetary system TOI 451 (TIC…
