摘要

本综述分为两部分。第一个是Barbier–Chalonge–Divan（BCD）分光光度系统，也称为巴黎光谱分类系统。尽管BCD系统已经被应用，并且仍然用于从O到F光谱类型的所有恒星物体，但目前的描述主要涉及正常和“活跃”的B型恒星。第二部分讨论了与恒星自转有关的主题，恒星自转被认为是决定恒星结构和演化的关键现象之一。第一部分非常注重观察。相比之下，第二部分涉及与恒星自转相关的观测方面，但也回顾了一些支持性或基本的理论概念，这些概念可能有助于更好地理解当今现有恒星数据解释的优点和缺点。

BCD Spectrophotometry and Rotation of Active B-Type Stars: Theory and Observations

This review has two parts. The first one is devoted to the Barbier–Chalonge–Divan (BCD) spectrophotometric system, also known as the Paris spectral classification system. Although the BCD system has been applied and is still used for all stellar objects from O to F spectral types, the present account mainly concerns normal and ‘active’ B-type stars. The second part treats topics related to stellar rotation, considered one of the key phenomena determining the structure and evolution of stars. The first part is eminently observational. In contrast, the second part deals with observational aspects related to stellar rotation but also recalls some supporting or basic theoretical concepts that may help better understand the gains and shortcomings of today’s existent interpretation of stellar data.
