J/A+A/523/A71       A and F stars abundances in the Hyades     (Gebran+, 2010)

Chemical composition of A and F dwarfs members of the Hyades open cluster. Gebran M., Vick M., Monier R., Fossati L. <Astron. Astrophys. 523, A71 (2010)> =2010A&A...523A..71G
ADC_Keywords: Clusters, open ; Stars, A-type ; Stars, F-type ; Abundances Keywords: stars: abundances - stars: chemically peculiar - stars: rotation - open clusters and associations: individual: Hyades - diffusion Abstract: Abundances of 15 chemical elements have been derived for 28 F and 16 A stars members of the Hyades open cluster in order to set constraints on self-consistent evolutionary models that include radiative and turbulent diffusion A spectral synthesis, iterative procedure was applied to derive the abundances from selected high-quality lines in high-resolution, high-signal-to-noise spectra obtained with SOPHIE and AURELIE at the Observatoire de Haute Provence. Description: In table 5 and 6, we present the abundances of 15 chemical elements in 16 A and 26 F stars members of the Hyades open cluster. These abundances are relative to hydrogen and to the sun. The abundances derived for procyon are also included. The absolute parameters for the observed stars as the luminosity, effective temperature, mass and fractional age (fraction of time spent on the Main Sequence) are displayed in table 7. Table 8 collects the abundances derived for each transition for each studied element in all A and F stars including Procyon (F5V) which served as control star for the spectral synthesis. In this table, the absolute values are represented (log(X/H)+12) and the wavelengths are in Angstrom. File Summary:
