Abstract:
We have obtained high-resolution spectroscopy of ten red giants in the
Carina dwarf spheroidal (dSph) galaxy with the ultraviolet and visual
echelle spectrograph at the European Southern Observatory Very Large
Telescope in order to study the detailed chemical evolution of this
Galactic satellite. Here we present the abundances of O, Na, Mg, Si,
Ca, Ti, and Fe.
Description:
Our data were obtained in the course of the ESO Large Programme
171.B-0520(A) (PI: G. F. Gilmore; see also Paper I; Wyse et al.,
2006ApJ...639L..13W 2006ApJ...639L..13W; Wilkinson et al., 2006Msngr.124...25W 2006Msngr.124...25W; Koch et
al., 2007AJ....133..270K 2007AJ....133..270K, for details) that aims at studying the
kinematic and chemical characteristics of Galactic dSphs.
