Derivation of stellar parameters using a grid of synthetic spectra.
Abstract
A grid of synthetic spectra is built, for a set of stellar parameters, in the spectral region λλ4780 - 5300 Å. Spectrophotometric indices in this region are chosen and measured in the synthetic spectra; these theoretical indices are directly compared to those measured in the observed spectra, in order to obtain the stellar parameters temperature, gravity and metallicity.
