Abstract

Generalized fitting formulas have been obtained describing the dependence “helium burning time–mass of zero-age stars” for stars belonging to populations I–III and having the corresponding masses and elemental composition. The approximation has been performed for nonrotating and rotating stars. The regularities in the obtained dependences have been revealed on the content Z of heavy chemical elements (ranging from 0 to 0.1), which include characteristic values for stellar populations I–III in the presence or absence of axial rotation.

I–III类恒星的氦气燃烧持续时间

摘要

已经获得了通用的拟合公式，描述了属于I-III族并具有相应质量和元素组成的恒星的“氦燃烧时间-零年龄恒星的质量”的相关性。已对非旋转恒星和旋转恒星进行了近似。已获得的相关性的规律性已经揭示出重化学元素的含量Z（从0到0.1），其中包括存在或不存在轴向旋转时恒星群体I–III的特征值。
