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.
