Description
We show our very first results regarding the stellar atmospheric
parameter determinations (T_{eff} , log g, [Fe/H]) of M-type stars
observed with CARMENES te{Carmenes} by means of the spectral synthesis
method. We have selected spectral ranges around iron and titanium lines
and molecular bands in three reference M-type stars: GX And (M1.0 V),
Luyten's star (M3.5 V),and Teegarden's star (M7.0 V). We employ PHOENIX
stellar model atmospheres te{Phoenix}, the radiative transfer code
TurboSpectrum te{TurboSpectrum} and line data from the VALD3 database
te{Vald} to obtain a grid of synthetic spectra, and a Markov Chain
Monte Carlo process implemented in SteParSyn code te{SteParSyn} to
derive the value of the stellar atmospheric parameters.
