Resumo
Stellar models are calculated in the approximation of a uniform density distribution. Variational method was used for determination of the boundary of a stability loss, for stellar masses in the range from 2 up to . The effects of the general relativity had been taken into account. The equation of state in the temperature and density ranges K, g/sm had been taken from the work of Imshennik and Nadyozhin (1965). The critical parameters for the values of entropy and stellar masses differ from more accurate values, obtained using a more complucated variant of accepted density distribution, not more than 12%.
