M dwarf spectral indices at moderate resolution: accurate 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 and metallicities [Fe/H] for M dwarfs, based on a Principal Component Ana…
Faint solar analogs: at the limit of no reddening
Riano E. Giribaldi, Gustavo F. Porto de Mello, Diego Lorenzo-Oliveira +2
The flux distribution of solar analogs is required for calculating the spectral albedo of Solar System bodies such as asteroids and trans-Neptunian objects. Ideally a solar analog…
Accurate effective temperature from H profiles
Riano E. Giribaldi, Maria L. Ubaldo-Melo, Gustavo F. Porto de Mello +4
The determination of stellar effective temperature () in F, G, and K stars using H profile fitting is a quite remarkable and powerful tool, because it practica…
