Descripción
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.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta
