摘要:

我们将回顾我们最近对O 9 IV星HD 57682的磁特性的分析,使用在大质量恒星(MiMeS)大计划的背景下在加拿大-法国-夏威夷望远镜的ESPaDONS获得的分光偏振观测。我们讨论了我们最近确定的旋转周期的纵向磁场测量和H_α的变化-后者获得了超过十年的专业和业余光谱观测的价值。最后,我们报告我们的调查的磁场的几何形状和影响的领域上的拱星环境。

英文摘要:

We will review our recent analysis of the magnetic properties of the O9IV star HD 57682, using spectropolarimetric observations obtained with ESPaDOnS at the Canada-France-Hawaii telescope within the context of the Magnetism in Massive Stars (MiMeS) Large Program. We discuss our most recent determination of the rotational period from longitudinal magnetic field measurements and H_alpha variability - the latter obtained from over a decade's worth of professional and amateur spectroscopic observations. Lastly, we report on our investigation of the magnetic field geometry and the effects of the field on the circumstellar environment.
