Atomic Data, Line: Identification, Stars: Chemically Peculiar
Scientific paper
The first theoretical transition probabilities are obtained for a set of 46 PmII transitions of astrophysical interest. These data fill in a gap in astrophysics and will allow to establish, on a firmer basis, the presence of some lines of this radioactive element in the spectra of chemically peculiar stars and, consequently, a quantitative investigation of the stellar Pm abundance. A search for PmII lines in Przybylski's star (HD 101065) and in HR 465 is reported and discussed, supporting the detection of this ion. A more detailed quantitative analysis is awaiting the availability of dedicated model atmospheres for these stars.
Based on spectra obtained on the VLT (ESO, Paranal, Chile) and retrieved from the ESO archives.
