晚型恒星中的类太阳活动(Ⅱ):活动色球、过渡区和冕区发射、耀发活动

Solar-like Activities in Late-type Stars( Ⅱ): Active Chromosphere,Transition Region and Coronal Emissions, and Stellar Flares

本文对晚型恒星的色球、过渡区和冕区的类太阳活动,恒星的耀发活动,及其与恒星的光谱型、自转、Rossby数、年龄等恒星基本参数的关系作了综合叙述,并对有关的物理问题和研究进展作了介绍。

This paper summarizes our present understanding of solar-like activities in flares of late-type stars from optical, UV and X-ray emissions. The remarkable progress has been made in the last decade on study of the empirical relationship between chromospheric and coronal fluxes and as well the correlations of the activities with stellar parameters such as the spectral type, rotation, Rossby number, age and so on. Possible explanations of them and some particular problems that are ripe for further investigation are also briefly described in this paper.
