Abstract
Abstract The elemental composition of the chemically peculiar star HR 6958 has been studied with emphasis on doubly ionized rare earths. A visual region spectrum taken with the ELODIE spectrograph at the Haute-Provence Observatory was analyzed. A total of 40 elements including Pr III, Nd III, Tb III, Dy III, Ho III, and Er III were identified and their abundances computed. He is deficient by over 1 dex with respect to the Sun; the light elements (C-Ca), except for Si, have solar abundances; the iron group elements (Sc–Fe) are overabundant by 1 dex to 2 dex, with Ti and Cr highly overabundant; and the lanthanide rare earths are overabundant by 3 dex to 4 dex. This abundance pattern with He deficient, Si, Ti, Cr, Sr, and Pr overabundant indicates that HR 6958 is a member of Si stars.
