Abstract:
We have used FLAMES (the Fibre Large Array Multi Element Spectrograph)
at the VLT-UT2 telescope to obtain spectra of a large sample of red
giant stars from the inner disk of the LMC, 2kpc from the center of
the galaxy. We investigate the chemical abundances of key elements to
understand the star formation and evolution of the LMC disk: heavy and
light [s-process/Fe] and [alpha/Fe] give constraints on the time
scales of formation of the stellar population. Cu, Na, Sc, and the
iron-peak elements are also studied aiming to better understand the
build up of the elements of this population and the origin of these
elements. We aim to provide a more complete picture of the LMC's
evolution by compiling a large sample of field star abundances.
LTE abundances were derived using line spectrum synthesis or
equivalent width analysis. We used OSMARCS model atmospheres and an
updated line list.
Description:
Photometric data, photometric and spectroscopic stellar parameters,
radial velocities, abundance errors, atomic data, chemical abundances
of alpha-, iron-peak and s-process elements, Cu and Na, and abundance
errors are given for a sample of 59 stars.
