Metallicity of M dwarfs. IV. A high-precision [Fe/H] and Teff technique from high-resolution optical spectra for M dwarfs.

Abstract (from CDS):

In this work we develop a technique to obtain high precision determinations of both metallicity and effective temperature of M dwarfs in the optical. A new method is presented that makes use of the information of 4104 lines in the 530-690 nm spectral region. It consists in the measurement of pseudo equivalent widths and their correlation with established scales of [Fe/H] and Teff. Our technique achieves a rms of 0.08±0.01 for [Fe/H], 91±13K for Teff, and is valid in the (-0.85, 0.26dex), (2800, 4100K), and (M0.0, M5.0) intervals for [Fe/H], Teff and spectral type respectively. We also calculated the RMSEV which estimates uncertainties of the order of 0.12 dex for the metallicity and of 293K for the effective temperature. The technique has an activity limit and should only be used for stars with logLHα/Lbol←4.0.
