摘要
扩展了关于处于“红巨星过渡阶段”质量范围内的恒星的演化计算。 presented for two values of the metallicity Z (Z=10E-4, 4E-4) and for ages down to 1 billion years, discussing selected evolutionary features characterizing the structure of the stars during both H or He burning phases. 发现，对于大约为1E-4的金属丰度且年龄在1-20亿年左右的星团，可能出现约LogL= 2.0-2.2（以太阳单位计）的异常He燃烧变星。
