理论模型计算的恒星上的氢燃烧低主序星质量小于或等于0.55太阳质量。特别注意的是大气层和包层的处理以及辐射不透明度和状态方程的选择。的模型属性的依赖外边界条件进行检查，使用两个独立的状态方程的确定构造的模型进行了详细的比较。据发现，理论上推断的质量小于约0.10太阳质量的恒星的属性可以根据假设的输入物理显着不同。参考文献63篇。
Theoretical models are calculated for stars on the hydrogen-burning lower main sequence having masses less than or equal to 0.55 solar mass. Particular attention has been paid to the treatment of the atmosphere and envelope and to the choice of the radiative opacities and equation of state. The dependence of the model properties on the outer boundary conditions is examined, with a detailed comparison of models constructed using two independent determinations of the equation of state. It is found that the theoretically inferred properties of stars of mass less than about 0.10 solar mass can differ noticeably depending on the assumed input physics. 63 refs.
