摘要:

对猎户座OB1星协中化学奇特(CP)恒星的详细光谱调查是迄今为止在SAO进行的恒星磁性领域最全面的观测计划。截至2018年底,我们已经完成了对该协会最古老的子组$\textit{a}$中CP星的测量。在本文中,我们给出了一个简短的概述CP成员的子群显示直接和间接的多重签名。在全部11颗被归类为特殊的恒星中,我们发现了几颗很好的候选恒星,可以进行进一步的详细研究。

英文摘要:

A detailed spectroscopic survey of chemically peculiar (CP) stars in the Orion OB1 association is the most comprehensive observational program in the field of stellar magnetism that has been carried out at SAO so far. As at the end of 2018, we have completed surveying CP stars in the oldest subgroup $\textit{a}$ of the association. In this paper, we give a short overview of CP members of the subgroup showing both direct and indirect signatures of multiplicity. Among the overall 11 stars which had been classified as peculiar, we found several good candidates for further detailed study.
