AN H -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 IRTF-SpeX spectrog...
