摘要
本文介绍了猎户座OB1星群中化学特殊恒星的物理参数(𝑇eff, log𝑔,𝐿,𝑀,𝑅,𝑣𝑒sin,𝑣𝑒)的研究结果。在SAO RAS的6 m BTA望远镜上获得了所有CP星的圆偏振辐射光谱材料。因此,在该协会的磁性和非磁性CP星之间没有发现统计学差异。旋转速度参数𝑣𝑒sin()的投影存在差异。然而,对赤道速度𝑣𝑒的详细研究表明,磁性的平均值与非磁性的Ap/Bp恒星没有区别。
Statistical physical parameter properties of Ap/Bp-stars in the Orion OB1 Association
The article presents the results of physical parameters ( 𝑇 eff , log 𝑔 , 𝐿 , 𝑀 , 𝑅 , 𝑣 𝑒 sin 𝑖 , 𝑣 𝑒 ) study for chemically peculiar stars in the Orion OB1 association. Spectral material of circularly polarized radiation for all CP stars was obtained at the 6-m BTA telescope in the SAO RAS. As a result, no statistical differences were found between magnetic and non-magnetic CP stars of the association. The difference was found for the projection of rotation velocity parameter 𝑣 𝑒 sin 𝑖 . However, a detailed study of the equatorial velocity 𝑣 𝑒 showed that the average value for magnetic does not differ from non-magnetic Ap/Bp stars.
