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...
