J/A+A/541/A143      NLTE Corrections of the Ca lines             (Spite+, 2012)

NLTE determination of the calcium abundance and 3D corrections in extremely metal-poor stars. Spite M., Andrievsky S.M., Spite F., Caffau E., Korotin S.A., Bonifacio P., Ludwig H.-G., Francois P., Cayrel R. <Astron. Astrophys. 541, A143 (2012)> =2012A&A...541A.143S
ADC_Keywords: Abundances ; Line Profiles Keywords: line: formation - line: profiles - stars: abundances - supernovae: general - Galaxy: evolution Abstract: Extremely metal-poor stars contain the fossil records of the chemical composition of the early Galaxy and it is important to compare Ca abundance with abundances of other light elements, that are supposed to be synthesized in the same stellar evolution phases. The NLTE profiles of the calcium lines were computed with a modified version of the program MULTI, which allows a very good description of the radiation field. Description: The NLTE corrections were computed for 51 CaI lines and 16 CaII lines for a grid of models with different metallicities from [Fe/H]=0.0 to [Fe/H]=-3. These corrections must be added to the LTE value of [Ca/H], they were computed only if the equivalent width of the Ca line was stronger than 3mÅ. In the tables the model is given in the form (Teff, logg, [Fe/H], [Ca/Fe]) where Teff is the effective temperature, and logg the logarithm of the surface gravity) File Summary:
