Abstract (from CDS):

A set of transition probabilities is obtained for the first time for many transitions of Pr III of astrophysical interest. A relativistic Hartree-Fock method, combined with a least-squares fitting of the available experimental levels, including a large number of newly determined values, has been used for the calculations in which configuration interaction and core-polarization effects have been introduced. The interest of the new data set is illustrated by considering the chemical composition of the chemically peculiar (CP) stars HD 101065 (Przybylski's star) and HD 141556 (χ Lupi).
