M dwarf spectral indices at moderate resolution: accurate $T_{eff}$ and [Fe/H] for 178 southern stars

E. Costa-Almeida, G. F. Porto de Mello, R. E. Giribaldi +2

We present a spectroscopic and photometric calibration to derive effective temperatures $T_{eff}$ and metallicities [Fe/H] for M dwarfs, based on a Principal Component Ana…

Titans metal-poor reference stars. I. Accurate effective temperatures and surface gravities for dwarfs and subgiants from 3D non-LTE H $α$ profiles and Gaia parallaxes

Riano E. Giribaldi, André R. da Silva, Rodolfo Smiljanic +1

Several large stellar spectroscopic surveys are producing overwhelming amounts of data that can be used for determining stellar atmospheric parameters and chemical abundances. None…
