Abstract:
We present the abundance measurements of several elements (Fe, Ca, Na,
Ni, Ti, Al, Cr, Si) for 20 solar-type stars belonging to four Galactic
open clusters: NGC 3680, IC 4651, Praesepe, and M 67. Oxygen
abundances were in addition measured for most stars in each cluster
apart from IC 4651. For NGC 3680, accurate abundance determinations
using high-resolution spectra covering a large spectral domain are
computed for the first time.
We used UVES high-resolution, high signal-to-noise (S/N) ratio spectra
and performed a differential analysis with respect to the sun, by
measuring equivalent widths and assuming LTE.
Description:
Line list used, from Randich et al. (2006A&A...450..557R 2006A&A...450..557R), including
EW measurements done therein, plus the resulting solar abundance
values, computed for each line using the OSMARCS code (Edvardsson et
al., 1993, Cat. J/A+A/275/101).
