Sažetak
Stark Full Widths at Half Maximum for 46 Co II multiplets have been calculated in Majlinger et al. (2018) by modified semiempirical method described in Dimitrijevi{;ć}; and Konjevi{;ć}; (1980). The calculated results have been used to investigate the importance of Stark broadening mechanism for Co II lines in A type star and DA and DB white dwarf atmospheres (Majlinger et al., 2020). Stark broadening parameters from this paper will enter in the STARK-B database (http://stark- b.obspm.fr/). Here, as an example of obtained results, the influence of Stark broadening on two multiplets of ionized cobalt in atmospheres of DA and DB white dwarfs has been shown. It has been demonstrated that Stark broadening is more significant for DB white dwarfs and for larger wavelengths.
