Title: | INTRIGOSS: A new Library of High Resolution Synthetic Spectra | Authors: | FRANCHINI, Mariagrazia MOROSSI, Carlo DI MARCANTONIO, Paolo Chavez, Miguel GES-Builders |
Issue Date: | 2018 | Volume: | Proceedings of Chemical and Dynamical Evolution of Galaxies | First Page: | 1 | Abstract: | INTRIGOSS (INaf Trieste Grid Of Synthetic Spectra) is a new High Resolution (HiRes) synthetic spectral library designed for studying F, G, and K stars. The library is based on atmosphere models computed with specified individual element abundances via ATLAS12 code. Normalized SPectra (NSP) and surface Flux SPectra (FSP), in the 4800-5400 Å wavelength range, were computed by means of the SPECTRUM code. The synthetic spectra are computed with an atomic and bi-atomic molecular line list including "bona fide" Predicted Lines (PLs) built by tuning loggf to reproduce very high SNR Solar spectrum and the UVES-U580 spectra of five cool giants extracted from the Gaia-ESO survey (GES). The astrophysical gf-values were then assessed by using more than 2000 stars with homogenous and accurate atmosphere parameters and detailed chemical composition from GES. The validity and greater accuracy of INTRIGOSS NSPs and FSPs with respect to other available spectral libraries is discussed. INTRIGOSS will be available on the web and will be a valuable tool for both stellar atmospheric parameters and stellar population studies. | Conference Name: | Chemical and Dynamical Evolution of Galaxies | Conference Place: | Sexten Center for Astrophysics (SCfA).
