Stark Broadening of Cr III Spectral Lines: DO White Dwarfs

Abstract Using the modified semiempirical method of Dimitrijevi？ and Konjevi？, Stark widths have been calculated for six Cr III transitions, for an electron density of 10 17 cm ？ 3 and for temperatures from 5000–80,000 K. Results have been used for the investigation of the influence of Stark broadening on spectral lines in cool DO white dwarf atmospheres. Calculated Stark widths will be implemented in the STARK-B database, which is also a part of the Virtual Atomic and Molecular Data Center (VAMDC). View Full-Tex
