摘要
本文在前文[1]研究的基础上对判断分光双星自转的同步性在理论上做了进一步改进。对双谱分光双星用视向速度曲线的半振幅K1和K2代替质量比q。对单谱分光双星除前文给出一种判断同步性方法外又给出两种方法。另外,用改进的公式对6对分光双星的同步性做了计算和判断。最后对所得结果做了讨论并用结束语对此项研究工作做了回顾和展望。
This paper provides certain theoretical improvement of the formulas for judging the synchronization of self rotations of stars in a spectroscopic binary system based on a previous paper. The improvement for the formulas of a double-line spectroscopic binary-star system is mainly in that the mass ratio q1.2 is replaced by the observable semi-amplitudes of the radial-velocity curve, K1.2. The author also supplies two methods for the formulas of single-line spectroscopic binary stars in addition to the method in the previous paper. The author lists the calculation and judgment results for the synchronization of self rotations in six spectroscopic binary systems with the new formulas. The results obtained are finally summarized, which leads to certain expectation about the future direction of such research.
