Non-LTE line formation for SII and SIII. I. Model atoms and first results.
VRANCKEN M., BUTLER K. and BECKER S.R.
Abstract (from CDS):
Detailed model atoms for SII and SIII are presented. As a test and first application of these models, the sulphur abundance of the B type stars HR 1923, HR 2928 and HR 5285 is derived.
Result. based on LTE computations are compared with those from a non-LTE analysis. For the three stars in the test sample, new values of effective temperature Teff, gravities logg and microturbulent velocities vturb, based on the latest Kurucz model atmospheres are also given. A new grid of H profiles and Si equivalent widths for these models is presented.
