An Ultra Metal-poor Star Near the Hydrogen-burning Limit
Kevin C. Schlaufman, Ian B. Thompson, Andrew R. Casey
It is unknown whether or not low-mass stars can form at low metallicity. While theoretical simulations of Population III (Pop III) star formation show that protostellar disks can f…
Thermohaline mixing in extremely metal-poor stars
Kate Henkel, Amanda I. Karakas, Andrew R. Casey +2
Extremely metal-poor (EMP) stars are an integral piece in the puzzle that is the early Universe, and although anomolous subclasses of EMP stars such as carbon-enhanced metal-poor (…
On the discovery of K-enhanced and possibly Mg-depleted stars throughout the Milky Way
Alex J. Kemp, Andrew R. Casey, Matthew T. Miles +8
Stars with unusual elemental abundances offer clues about rare astrophysical events or nucleosynthetic pathways. Stars with significantly depleted magnesium and enhanced potassium…
The R-Process Alliance: Chemical Abundances for a Trio of R-Process-Enhanced Stars -- One Strong, One Moderate, One Mild
Madelyn Cain, Anna Frebel, Maude Gull +9
We present detailed chemical abundances of three new bright (V ~ 11), extremely metal-poor ([Fe/H] ~ -3.0), r-process-enhanced halo red giants based on high-resolution, high-S/N Ma…
Chemical inhomogeneities in the Pleiades: signatures of rocky-forming material in stellar atmospheres
Lorenzo Spina, Jorge Meléndez, Andrew R. Casey +2
The aim of Galactic archaeology is to recover the history of our Galaxy through the information encoded in stars. An unprobed assumption of this field is that the chemical composit…
Gaia-ESO Survey: INTRIGOSS - A new library of High Resolution Synthetic Spectra
Mariagrazia Franchini, Carlo Morossi, Paolo Di Marcantonio +19
We present a high resolution synthetic spectral library, INTRIGOSS, designed for studying FGK stars. The library is based on atmosphere models computed with specified individual el…
