AN <i>H</i> -BAND SPECTROSCOPIC METALLICITY CALIBRATION FOR M DWARFS
We present an empirical near-infrared (NIR) spectroscopic method for estimating M dwarf metallicities, based on features in the H band, as well as an implementation of a similar published method in the K band. We obtained R ∼ 2000 NIR spectra of a sample of M dwarfs using the NASA …
