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…
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…
Infrared colours and inferred masses of metal-poor giant stars in the Kepler field
Andrew R. Casey, Grant M. Kennedy, Tom R. Hartle +1
Intrinsically luminous giant stars in the Milky Way are the only potential volume-complete tracers of the distant disk, bulge, and halo. The chemical abundances of metal-poor giant…
Evidence of an Upper Bound on the Masses of Planets and its Implications for Giant Planet Formation
Kevin C. Schlaufman
Celestial bodies with a mass of M ~ 10 M_Jup have been found orbiting nearby stars. It is unknown whether these objects formed like gas-giant planets through core accretion or like…
