Abstract

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 ±100 K and a surface gravity of log g = 1.0 ± 0.5 corresponding to a spectral type G(2-3)I. These parameters result in an estimated luminosity of 970 L⊙ and a distance of 2700pc. We also show that IRAS 05381 + 1012 has a projected rotational velocity v sini = 40 ±10km s-1. 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. © ESO 2006.
