热星磁场的观测

Observations of magnetic fields in hot stars

V. Petit

摘要:

几十年来,人们一直怀疑许多大质量恒星表面存在磁场,以解释观测到的OB星的性质和活动。然而,在新一代强大的分光偏振仪出现之前,很少有真正的大质量恒星被确定为磁性的,这导致了关于大质量恒星磁性的精确信息的快速爆发。在这次演讲中,我将简要回顾用于诊断高质量恒星磁场的现代方法,并总结我们目前对OB星磁特性的理解。

英文摘要:

The presence of magnetic fields at the surfaces of many massive stars has been suspected for decades, to explain the observed properties and activity of OB stars. However, very few genuine high-mass stars had been identified as magnetic before the advent of a new generation of powerful spectropolarimeters that has resulted in a rapid burst of precise information about the magnetic properties of massive stars. During this talk, I will briefly review modern methods used to diagnose magnetic fields of higher-mass stars, and summarize our current understanding of the magnetic properties of OB stars.
