great interest for exoplanet searches. The presence of molecules in their atmosphere
complicates our understanding of their atmospheric properties. But great advances have
recently been made in the modeling of M dwarfs due to the revision of solar abundances.
Aims. We aim to determine stellar parameters of M dwarfs using high resolution spectra (R∼
90 000) simultaneously in the visible and the near-infrared. The high resolution spectra and …
