M-Dwarfs, Cool Atmosphere Models
Scientific paper
We present a comparison of low-resolution spectra of 60 stars covering the whole M-dwarf sequence. Using the most recent PHOENIX stellar atmosphere models we do a first quantitative comparison to our observed spectra in the wavelength range 500-900 nm. We perform a first confrontation between models and observations and we assign an effective temperatures to the observed M-dwarfs. Teff-spectral type relations are then compared with the published ones. This comparison also aims at improving the models.
