PublicationAn attempt to derive Mg isotopic ratios in carbon stars
We discuss the use of the spectral range near 7570 Å to determine the Mg isotopic ratios in carbon stars using the B'2 Sigma +-X 2 Sigma + system of the MgH...

PublicationAn Intermediate-age Alpha-rich Galactic Population in K2
We explore the relationships between the chemistry, ages, and locations of stars in the Galaxy using asteroseismic data from the K2 mission and spectroscopic...

PublicationBACCHUS Analysis of Weak Lines in APOGEE Spectra (BAWLAS)
Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure...

PublicationChemical Analysis of the Brightest Star of the Cetus II Ultrafaint Dwarf Galaxy Candidate
We present a detailed chemical abundance analysis of the brightest star in the ultrafaint dwarf (UFD) galaxy candidate Cetus II from high-resolution Magellan...

PublicationCu and Zn abundances in metal-poor stars
We present Cu and Zn abundances for a sample of 30 stars spanning a metallicity range between solar and [Fe/H]=-3. LTE abundances were obtained using Kurucz...

PublicationDetailed Chemical Abundances for a Benchmark Sample of M Dwarfs from the APOGEE Survey
Individual chemical abundances for 14 elements (C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are derived for a sample of M dwarfs using high...

PublicationEvidence for Evolved Stellar Binary Mergers in Observed B-type Blue Supergiants
Blue supergiants are the brightest stars in their host galaxies, and yet their evolutionary status has been a long-standing problem in stellar astrophysics. In...
