球状星团中射电双星的轨道参数与恒星相互作用

Orbital parameters of binary radio pulsars in globular clusters and stellar interactions

Manjari Bagchi, Alak Ray

摘要:

观测到的球状星团射电双星在偏心率-轨道周期平面上的分布可以解释为双星-单星相互作用的结果。我们的数值和分析研究表明,最高偏心率的双星在集群中可能是从交换和/或合并的一个单一的明星与一个二元组件,而中间偏心率系统可能是飞的结果。

英文摘要:

The observed distribution of globular cluster binary radio pulsars in the eccentricity versus orbital period plane can be explained as a result of binary-single star interactions. Our numerical and analytical study hints that the highest eccentricity binaries in clusters are likely to be from exchange and/or merger of a single star with a binary component, while the intermediate eccentricity systems are probably results of fly-by interactions.
