仙女座发射星云和α Sco A的质量损失

The Antares emission nebula and mass loss of alpha Sco A

D. Reimers, H. -J. Hagen, R. Baade, K. Braun

摘要:

星云是一个奇特的发射星云,可以看到大量的Fe II谱线和射电自由-自由发射,可能与α-Sco A风中的α-Sco B引起的H II区有关。具有空间分辨率的高分辨率光谱被用来研究M超巨星α Sco A的发射线光谱和星云的物理性质,并确定其质量损失率。

英文摘要:

The Antares nebula is a peculiar emission nebula seen in numerous Fe II lines and in radio free-free emission, probably associated with the H II region caused by alpha Sco B in the wind of alpha Sco A. High-resolution spectra with spatial resolution were used to study the emission line spectrum, the physical nature of the nebula and to determine the mass-loss rate of the M supergiant alpha Sco A.
