Bp-and Ap-stars in moving Scorpio-Centaurus cluster.
Abstract
The degree and type of peculiarity as well as quantitative spectral types and rotation velocities are defined for 10 peculiar stars and for 4 stars of Vb luminosity class from the Scorpio-Centaurus cluster. Effective temperatures (Te) and surface gravities (lg g) are obtained for 29 peculiar stars from this cluster. It is shown that lg g values for the stars of Vb luminosity class are by 0.2 - 0.4 larger than those for the stars on the zero-age main sequence.
