Near-infrared spectroscopy of M dwarfs. I. CO molecule as an abundance indicator of carbon
Based on the near-infrared spectra of 42 M dwarfs, carbon abundances are determined from the ro-vibrational lines of the CO (2–0) band. We apply Teff values based on the angular diameters if available or use the Teff values in a log Teff–M3.4 relation (M3.4 is the absolute magnitude at 3.4 μm based...
