标题： Recent developments in determining the evolution of magnetic OB stars

摘要： 我们回顾了确定磁性大质量OB星演化的最新进展。 一个重要科学问题是同时光谱偏振调查在赫罗图中的完整性和检测极限。 我们介绍了O型星MiMeS调查的特性，以及当前可用观测的限制如何促使设计新的高精度调查，以针对较老的O型星群体。 另一个重要问题是磁场的存在是否以显著方式改变恒星演化轨迹，从而导致恒星参数的错误确定。 我们回顾了包含磁场风抑制效应和铁不透明度峰值区对流抑制的新演化模型。 显示英文摘要

摘要： 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.
