摘要
耀星是红矮星早期演化的一个必经阶段，这个阶段的持续时间取决于恒星的质量。在年轻和比较年轻的疏散星团（和星协）中，都含有大量耀星，它们的光度分布是疏散星团（或星协）年龄的标志。在昂星团中已发现大星耀星，对它们的自行、测光和分光资料进行深入的统计研究，对于解决疏散星团及矮星起源和演化问题，有着极其重要的价值。
The stage of flare stars, which duration depends on the mass of the stars, is a natural stage of the early evolution for red dwarf stars. Any young or relatively young open cluster (or association) contains a great nulnber of flare stars and their luminosity distribution is an index of age of the cluster (or association). In particular, a great number of flare stars have been found in the Pleiades and the further comprehensive statistics on the proper motions and the photometric and spectroscopic data for these stars are very important to solve the problem about tlle origin and evolution of the open clusters and dwarfs.
