OCCAM X. Neutron Capture Abundances with Keck/HIRES & Magellan/MIKE
Natalie R. Myers, Peter M. Frinchaboy, Henrique Reggiani +10
The chemistry of stars provides powerful insight into the history of the Milky Way. With multiple large-sky spectroscopic surveys that are currently available, using chemistry as a…
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…
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…
Enrichment by Extragalactic First Stars in the Large Magellanic Cloud
Anirudh Chiti, Mohammad Mardini, Guilherme Limberg +8
The Large Magellanic Cloud (LMC) is the Milky Way's most massive satellite galaxy, which only recently (~2 billion years ago) fell into our Galaxy. Since stellar atmospheres preser…
The Dependence of Iron-rich Metal-poor Star Occurrence on Galactic Environment Supports an Origin in Thermonuclear Supernova Nucleosynthesis
Zachary Reeves, Kevin C. Schlaufman, Henrique Reggiani
It has been suggested that a class of chemically peculiar metal-poor stars called iron-rich metal-poor (IRMP) stars formed from molecular cores with metal contents dominated by the…
A non-interacting Galactic black hole candidate in a binary system with a main-sequence star
Sukanya Chakrabarti, Joshua D. Simon, Peter A. Craig +10
We describe the discovery of a solar neighborhood (d=468 pc) binary system with a main-sequence sunlike star and a massive non-interacting black hole candidate. The spectral energy…
The Most Metal-poor Stars in the Magellanic Clouds are -process Enhanced
Henrique Reggiani, Kevin C. Schlaufman, Andrew R. Casey +2
The chemical abundances of a galaxy's metal-poor stellar population can be used to investigate the earliest stages of its formation and chemical evolution. The Magellanic Clouds ar…
