摘要
本文对经典耀星和RS CVn型双星中的耀发现象作了综述。在总结有关耀发的观测统计特征的基础上,对各种有关耀发的物理模型作了分析,并与包括近年来用多波段对耀发的监测在内的观测作了比较。许多研究者认为,恒星的耀发类似于太阳白光耀发,它的光学辐射是类黑体的,来自较深的色球层和一定的耀发面积。本文亦从类太阳活动的观点,讨论了有关耀发能量释放的过程和加热机制的问题。
The present review is given of stellar flares in classical flare stars as well as the RS CVn binary stars. Based on their statistical properties, various physical models of flares are analysed in comparison with observations including recent multi-wavelength monitoring. It is argued by many researchers that the stellar flare is something similar to solar white flare and its optical radiation is of quasi-black-body and from deep chromosphere with limited emission area.The questions about how to understand the energy release processes and the heating mechanism are discussed in the view of solar-stellar connection.
