Spectral atlas of A-type supergiants

V. G. Klochkova, E. G. Sendzikas, E. L. Chentsov

摘要:

利用6米BTA望远镜和中阶梯光谱仪NES的高光谱分辨率观测(R=60000),研究了三颗A型超巨星的光谱:一颗奇特的超巨星3 Pup,一颗后AGB星BD+48 1220和一颗大质量的$α$ Cyg,它们属于本质上不同的演化阶段。这些恒星的光谱图谱是在3920至6720波长范围内准备的。

英文摘要:

Based on high-spectral-resolution observations (R=60000) performed with the 6-m BTA telescope in combination with the echelle spectrograph NES, we have studied the optical spectra of three A-type supergiants: a peculiar supergiant 3 Pup, a post-AGB star BD+48 1220, and a massive $α$ Cyg, which belong to essentially different stages of evolution. A spectral atlas for these stars is prepared in the wavelength interval of 3920 to 6720 Å.
