In order to show the applicability and usefulness of this set of data for research into white dwarf and A type star atmospheres, the obtained results were used to investigate the significance of the Stark broadening mechanism for Co II lines in the atmospheres of these objects. We examined the influence of surface gravity (log g), effective temperature and the wavelength of the spectral line on the importance of the inclusion of Stark broadening contribution in the profiles of the considered Co II spectral lines, for plasma conditions in atmospheric layers corresponding to different optical depths.<\/jats:p>","DOI":"10.3390\/data5030074","type":"journal-article","created":{"date-parts":[[2020,8,27]],"date-time":"2020-08-27T08:05:18Z","timestamp":1598515518000},"page":"74","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Stark Broadening of Co II Lines in Stellar Atmospheres"],"prefix":"10.3390","volume":"5","author":[{"given":"Zlatko","family":"Majlinger","sequence":"first","affiliation":[{"name":"Astronomical Observatory, Volgina 7, 11060 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9138-8642","authenticated-orcid":false,"given":"Milan S.","family":"Dimitrijevi\u0107","sequence":"additional","affiliation":[{"name":"Astronomical Observatory, Volgina 7, 11060 Belgrade, Serbia"},{"name":"Sorbonne Universit\u00e9, Observatoire de Paris, Universit\u00e9 PSL, CNRS, F-92195 Meudon, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7938-5748","authenticated-orcid":false,"given":"Vladimir A.","family":"Sre\u0107kovi\u0107","sequence":"additional","affiliation":[{"name":"Institute of Physics Belgrade, University of Belgrade, 11001 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,27]]},"reference":[{"key":"ref_1","first-page":"335","article-title":"On the cobalt abundances of early-type stars","volume":"353","author":"Adelman","year":"2000","journal-title":"Astron.
