Detailed analysis of nearby bulgelike dwarf stars. I. Stellar parameters, kinematics, and oxygen abundances.

POMPEIA L., BARBUY B. and GRENON M.

Abstract (from CDS):

High-resolution échelle spectra were obtained with the Fiber-fed Extended Range Optical Spectrograph at the 1.5 m ESO telescope for 35 nearby bulgelike stars with metallicities in the range -0.8≤[Fe/H]≤+0.4. Geneva photometry, astrometric data from Hipparcos, and radial velocities from CORAVEL are available for these stars. From Hipparcos data, it appears that the turnoff of this population indicates an age of 10-11 Gyr (as stated by Grenon in 1999). Detailed analysis of the sample stars is carried out, and atmospheric parameters derived from spectroscopic and photometric determinations are presented. Oxygen abundances are derived based on the forbidden [O I] 6300.3 Å line. The results show an oxygen overabundance pattern for most of the sample stars when compared to their disk counterparts.
