Abstract:
We present the elemental abundances of a large sample of F and G
dwarfs in the solar neighborhood. The analysis is based on
high-resolution spectra obtained with MIKE on the Magellan telescope,
FEROS on the ESO 1.5m and 2.2m telescopes, HARPS on the ESO 3.6m
telescope, UVES on the ESO Very Large Telescope, SOFIN and FIES on the
Nordic Optical Telescope. We focused our study on odd-Z iron-peak
elements Sc, V, Mn and Co. Our results show that Sc, V, and Co present
similar trend as the alpha elements and in Co case, this is true also
when non-local thermodynamic equilibrium corrections (non-LTE, NLTE)
are applied. On the contrary Mn is generally underabundant relative
the Sun but when NLTE corrections are applied the trend is basically
flat with [Mn/Fe]=0. Considering the age as selection criterion for
thin and thick disk we did not find any difference for V, Co, and Mn
LTE while for Sc and Mn NLTE a small difference seem to be present.
Comparisons with the alpha-element Ti show flat trends for all the
elements except Mn that present well separated [Mn/Ti]-[Ti/H] for thin
and thick disk.
Description:
In the following tables we provide stellar parameters for the sample,
abundances for the single lines analysed and detailed abundances for
Sc, V, Mn, and Co together with NLTE corrections for Mn and Co.
