确定磁OB星演化的最新进展
Recent developments in determining the evolution of magnetic OB stars
摘要：
我们回顾了最近的发展，在确定大质量OB星的演化。其中一个重要的科学问题是完整性和检测限的同期分光偏振调查的HR图。我们提出的特点的MiMeS调查的O型恒星，以及如何限制目前可用的观测保证设计新的高精度的调查，针对较老的O型恒星人口。另一个重要的问题是，磁场的存在是否会显著改变恒星的演化轨迹，从而导致恒星参数的错误测定。我们回顾了新的演变模型，包括磁风淬火的效果，和抑制对流的铁不透明峰区。
英文摘要：
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.
