| Description | Basic parameters of the atmospheres (i.e., Teff, log g, [A/H], vturb) of four late type giant stars alpha Ari, alpha Boo, alpha Cas, beta Gem are obtained by matching synthetic spectra to observed ones. We used model atmosphere to compute the synthetic spectrum. The parameters of the model atmosphere and of the synthetic spectrum are fitted to match the observed spectrum, accelerated by means of a proposed numerical tool. |
