- 我们用美国McDonald天文台2.1米反光镜Coude Reticon观测,对31个RS CVn型双星系统的37颗子星的自转进行了测量。High signal-to-noise spectral observations were taken in red region by use of the coude Reticon attached to the 2.1 m reflector at McDonald Observatory ia November and December, 1984. Following the former studying [ 4 ] , we analyse the rotation for 37 stars from 31 RS CVn binary star systems.
