  The limiting mass of cold white dwarfs was first calculated by E. Stoner in
an approximate model of a uniform star and was soon reduced by ~20% in papers
by S. Chandrasekhar and L. D. Landau based on an exact solution of the
equations for the stellar equilibrium. Here we examine uniform models of white
dwarfs taking general relativity effects and the influence of finite
temperature into account. Solutions are obtained in the form of finite analytic
formulas and, for masses differing by no more than ~20% from the exact
solutions, found by numerical integration of the differential equations for the
stellar equilibrium.
