论文摘要
我们回顾了确定磁性大量OB恒星演变的最新发展。重要的科学问题之一是整个人力资源图上的同期光谱法调查的完整性和检测极限。我们介绍了O-Type恒星的MIMES调查的特征，以及当前可用观测值的限制是否需要设计针对较旧的O型恒星种群的新的高精度调查。另一个重要的问题是，磁场的存在是否以重要的方式改变了恒星进化轨道，因此导致对恒星参数的错误确定。我们回顾了新的演化模型，其中包括磁风的效果以及在铁不透明度峰区中对流的抑制。
We review recent developments in determining the evolution of magnetic massive OB stars. One of the important scientific questions is the completeness and the detection limits of contemporaneous spectropolarimetric surveys across the HR diagram. We present the characteristics of the MiMeS survey of O-type stars, and how the limits of the current available observations warrant the design of new high-precision surveys that target the older O-type star population. Another important question is whether the presence of the magnetic fields changes stellar evolutionary tracks in a significant way, hence leading to a wrong determination of stellar parameters. We review new evolution models that include the effect of magnetic wind quenching, and suppression of convection in the iron opacity peak zone.
