A Test of FeH Line Parameters using DR19 APOGEE spectra of Benchmark M Dwarfs
Anderson Silva-Andrade, Diogo Souto, Katia Cunha +9
Recent studies have suggested a mismatch of up to 0.20 dex between iron abundances derived from Fe I and FeH lines in the H-band spectra of M dwarfs, and in this work we investigat…

A metallicity scale derived from Fe I and FeH lines in the APOGEE M dwarf spectra
Anderson da Silva-Andrade, Diogo Souto
We present metallicities derived from a sample of eleven M dwarfs belonging to wide binary systems with warmer FG primary companions observed by the high-resolution (R=22,500) near…
