摘要

上层主序的磁性化学特殊恒星正在缓慢旋转早期B到早期f型天体，与太阳相比，元素过剩数个数量级。驱动机制是在平静的恒星大气中扩散，稳定的有组织磁场的存在加强了扩散。二元分数对于理解这些天体的形成和演化以及可能的角动量损失机制至关重要。本文回顾了有关二进制分数的现有文献，并列出了未来需要的工作步骤。

Binary fraction of magnetic chemically peculiar stars

Magnetic chemically peculiar stars of the upper main sequence are slowly rotating early B to early F-type objects with elemental overabundances of several orders of magnitude compared to the Sun. The driving mechanism is diffusion in the calm stellar atmosphere intensified by the presence of a stable organized magnetic field. The binary fraction is vital to understanding the formation and evolution of these objects as well as possible operating angular momentum loss mechanisms. The available literature on the binary fraction is reviewed and a list of needed future working steps is presented.
