Bibliographic description in the original language

Galeev A.I. A Study of Chemical Composition of δ Scuti-Type Stars Based on the Observations with the BTA and RTT-150 / A.I. Galeev, V.M. Berdnikova, D.V. Ivanova, D.O. Kudryavtsev, N.N. Shimanskaya, V.V. Shimansky, M.O. Balashova // ASP Conf. Ser. - 2017. – V.510. – P.199-203.

Annotation

The results of a study for a sample of the \delta Scuti-type stars according to the observations at the telescopes BTA and RTT-150 are submitted. Based on the photometric data the fundamental parameters of all studied stars are identified and analyzed. For the eight stars (for two of them the first time) using spectroscopic observations the fundamental parameters of the atmospheres (Teff, log g, [Fe/H]) and the chemical composition for 29 elements in the LTE-approximation are received. The chemical composition analysis demonstrates both the solar abundances of chemical elements and the anomalies of chemical composition typical for Am-stars in the studied sample of the \delta Scuti-type stars.
