A Detailed Chemical Study of the Extreme Velocity Stars in the Galaxy
Tyler Nelson, Keith Hawkins, Henrique Reggiani +3
Two decades on, the study of hypervelocity stars is still in its infancy. These stars can provide novel constraints on the total mass of the Galaxy and its Dark Matter distribution…
The Galactic Distribution of Phosphorus: A Survey of 163 Disk and Halo Stars
Z. G. Maas, K. Hawkins, N. R. Hinkel +3
Phosphorus (P) is a critical element for life on Earth yet the cosmic production sites of P are relatively uncertain. To understand how P has evolved in the solar neighborhood, we…
The Chemical Composition of Extreme-Velocity Stars
Henrique Reggiani, Alexander P. Ji, Kevin C. Schlaufman +5
Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the Milky Way and surrounding dwarf galaxies chemical evolution history allows us to use t…
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…
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…
