The Chemical Compositions of the Type II Cepheids -- The BL Her and W Vir Variables
Thomas Maas, Sunetra Giridhar, David L. Lambert
Abundance analyses from high-resolution optical spectra are presented for 19 Type II Cepheids in the Galactic field. The sample includes both short-period (BL Her) and long-period…
Keplerian discs around post-AGB stars: a common phenomenon?
S. De Ruyter, H. Van Winckel, T. Maas +3
Aims: We aim at showing that the broad-band SED characteristics of our sample of post-AGB stars are best interpreted, assuming the circumstellar dust is stored in Keplerian rotatin…
A spectroscopic study of southern (candidate) gamma Doradus stars. I. Time series analysis
P. De Cat, L. Eyer, J. Cuypers +9
We present results of a spectroscopic study of 37 southern (candidate) gamma Doradus stars based on echelle spectra. The observed spectra were cross-correlated with the standard te…
IRAS 08544-4431 : a new post-AGB star in a binary system surrounded by a dusty disc
T. Maas, H. Van Winckel, T. Lloyd Evans +5
We present an analysis of our extensive data-set on IRAS 08544-4431. It is the first object we discuss of our newly defined sample of stars, selected for their position in the 'RV…
