Spectroscopic observations of the rapid rotating post-AGB star IRAS 05381+1012.


Abstract (from CDS):

We report on the high-resolution stellar parameters and abundance analysis of the rapidly rotating post-AGB star IRAS 05381+1012. Analysis of high-resolution spectra shows that IRAS 05381+1012 has an effective temperature of Teff=5200± 100K and a surface gravity of logg=1.0±0.5 corresponding to a spectral type G(2-3)I. These parameters result in an estimated luminosity of 970L and a distance of 2700pc. We also show that IRAS 05381+1012 has a projected rotational velocity vsini=40±10km/s. The abundance analysis based on a few available lines reveals that this star is an iron-deficient object with [Fe/H]=-0.8. We also analyze the abundance pattern and compare it to other classes of stars with similar stellar parameters.
