stellar activity meaning in Chinese

恒星活动性

Furthermore , we also reserch the influence of setllar age to stellar activity of late - type stars . the relation of stellar chromospheric activity and rotation of late - type main sequence stars depend on stellar spectral type
大样本分析显示晚型主序恒星的色球活动与恒星自转参量的研究晚型主序恒星的色球活动与恒星自转参量间的关系表现出对恒星光谱型的依赖。
We have collected a mass of stellar activity and rotation data of late - type stars . combining with the results of hipparcos satellite , we reserch the relation between stellar activity and rotation ( include rotation period and rossby number ) , and discuss the distribution of stellar rotation period and the evolution of angle momentum of late - type stars
因此，我们收集了晚型恒星的色球和冕球活动的指数以及恒星自转方面研究发表的大量的观测资料并结合hipparcos卫星的观测结果，对晚型恒星的磁活动与恒星自转间的相关性进行细致的研究。
