... determined for the mass M = 1.6 M , provided the initial angular momentum L0 . We consider in this work two different values of the initial angular momentum. For L0 = 1.8 × 1049 g · cm2 · s−1 we obtain the initial values for the semi-axes of the ellipsoid a1 (0) = 2.05 × 106 cm, a2 (0) = 1.59 × 106 ...

... It is straightforward to show that both the heat flux and luminosity vary as the 3/2 power of the difference of the actual temperature gradient from the purely adiabatic one (e.g., Ref. @Ref.Clayton@, p. 257). Typically, near the outside of a star, this difference is only 10−6 of the temperature gra ...
