cds-question@unistra.frvisible-astronomyspectroscopym-starsstellar-spectral-typesmetallicityWe present the homogeneous analysis of a sample of Southern early-type M dwarfs in the solar neighborhood (d<60pc). We used the MCAL technique to derive the effective temperature Teff, metallicity [Fe/H], and activity index i_a_(H_alpha_) of 420 M stars using HARPS spectra. The effective temperature Teff, surface gravity logg, metallicity [Fe/H], and projected rotational velocity V_rot_sini of 153 M0-M6 dwarfs were determined by fitting the observed intermediate-resolution spectra from the VIS arm of VLT/X-shooter with a grid of BT-Settl stellar atmosphere models. We estimated the typical uncertainties of the fit with X-shooter spectra by varying region-to-region results by {sigma}T_eff_~50K, {sigma}logg~0.2, and {sigma}[Fe/H]~0.2dex. Photometric verification of Teff for the 295 stars from the HARPS sample and the 61 stars from the X-shooter sample is also provided. We compared our results from different methods to estimate absolute uncertainty in determining the physical properties of M dwarfs.2019ApJ...878..134Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/878/134CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)J/AJ/131/1184 : A recalibration of opt. photometry (Maiz-Apellaniz+, 2006)J/A+A/492/277 : Analysis of Collinder 69 stars with VOSA (Bayo+, 2008)J/MNRAS/389/585 : Fundamental parameters of M dwarfs (Casagrande+, 2008)J/AJ/142/138 : All-sky catalog of bright M dwarfs (Lepine+, 2011)J/PASP/124/140 : UBVRI Hp BT and VT photonic responses (Bessell+, 2012)J/ApJ/757/112 : Stellar diameters.
