Detailed abundances of the planet-hosting TOI-1173 A/B system: Possible evidence of planet engulfment in a very wide binary

Jhon Yana Galarza, Henrique Reggiani, Thiago Ferreira +7

Over the last decade, studies of large samples of binary systems identified chemical anomalies, and showed that they might be attributed to planet formation or planet engulfment. H…

Accurate, Precise, and Physically Self-consistent Ages and Metallicities for 400,000 Solar Neighborhood Subgiant Branch Stars

David M. Nataf, Kevin C. Schlaufman, Henrique Reggiani +1

Age is the most difficult fundamental stellar parameter to infer for isolated stars. While isochrone-based ages are in general imprecise for both main sequence dwarfs and red giant…

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 Symbiotic X-ray Binary IGR J16194-2810: A Window on the Future Evolution of Wide Neutron Star Binaries From Gaia

Pranav Nagarajan, Kareem El-Badry, Casey Lam +1

We present optical follow-up of IGR J16194-2810, a hard X-ray source discovered by the INTEGRAL mission. The optical counterpart is a red giant at a distance of…

The Galactic Bulge exploration III.: Calcium Triplet Metallicities for RR Lyrae Stars

Andrea Kunder, Zdenek Prudil, Claire Skaggs +5

RR Lyrae stars are excellent tracers of stellar populations for old, metal-poor components in the Milky Way Galaxy and the Local Group. Their luminosities have a metallicity-depend…

Chemical Diversity on Small Scales -- Abundance Analysis of the Tucana V Ultra-Faint Dwarf Galaxy

Terese T. Hansen, Joshua D. Simon, Ting S. Li +5

The growing number of Milky Way satellites detected in recent years has introduced a new focus for stellar abundance analysis. Abundances of stars in satellites have been used to p…
