Spectroscopic analysis of barium dwarfs
Abstract
Spectroscopic analysis was performed for four dwarf stars in the literature referred to as barium stars. It was shown that HD 25475 has no notable overabundance of barium. Enhanced barium lines in spectrum of HD 124570 are probably caused by photospheric active regions, and in case of HD 198583 by effects of rapid rotation. The only star, HD 204613, can be attributed to classical barium stars.
