J. H. Grunhut, G. A. Wade, D. A. Hanes, E. Alecian

摘要:

我们提出了一个正在进行的调查的结果,冷,晚型超巨星-大质量的O-和B-型恒星的后代-系统地检测磁场在这些恒星使用光谱偏振观测与ESPaDONS在加拿大-法国-夏威夷望远镜。我们的观察揭示了可检测的,往往是复杂的,斯托克斯V塞曼签名在最小二乘去卷积的平均线配置文件中的一个显着的部分观察到的样本~30颗恒星。

英文摘要:

We present the results of an ongoing survey of cool, late-type supergiants - the descendants of massive O- and B-type stars - that has systematically detected magnetic fields in these stars using spectropolarimetric observations obtained with ESPaDOnS at the Canada-France-Hawaii Telescope. Our observations reveal detectable, often complex, Stokes V Zeeman signatures in Least-Squares Deconvolved mean line profiles in a significant fraction of the observed sample of ~30 stars.
