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…
