Titolo: | VizieR Online Data Catalog: Lick indices for FGK stars (Franchini+, 2014) | Autori: | FRANCHINI, Mariagrazia MOROSSI, Carlo DI MARCANTONIO, Paolo Malagnini, M. L. Chavez, M. |
Data pubblicazione: | 2015 | Rivista: | VizieR Online Data Catalog | Da pagina:: | J/MNRAS/442/220 | Abstract: | The stars observed by FEROS and studied by the AMBRE project (Worley et al., 2012A&A...542A..48W) constitute an ideal working data set for our purposes since they include a large number of non-supergiant FGK stars with individual estimates of Teff, log g, [M/H], and α-to-iron ratio ([alpha/Fe]). <P />We searched the European Southern Observatory (ESO) Science Archive Facility and retrieved, through the FEROS/HARPS pipeline processed data Query Form, all the public available spectra of FGK stars with AMBRE atmospheric parameter values in the following ranges: 3800<Teff<7500K, logg>3.5, and global metallicity [M/H]>-3.0. <P />A list of 1085 stars, corresponding to 2511 available spectra, was obtained. Since AMBRE provides individual estimates of stellar parameters derived from each spectrum, we computed for 202 stars with more than one observed spectrum average atmospheric parameter values. In any case, the dispersion of values for the same object resulted to be less than the external errors associated with AMBRE results. <P />(1 data file). <P /> | Note: | PRIN MIUR 2010–2011 project ‘The Chemical and Dynamical Evolution of the Milky Way and Local Group Galaxies’, prot. 2010LY5N2T. | URI: | http://hdl.handle.net/20.500.12386/23563 | URL: | http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=J/MNRAS/442/220 | Bibcode ADS: | 2015yCat..74420220F | Fulltext: | open |
