Scientific paper

An analytical stellar model is presented, that describes the Main-Sequence evolution of a fully-mixed star in terms of its hydrogen abundance X as a free parameter. The model employs a reasonably accurate approximation to the mean molecular weight by the function mu(x) = 2(1 + X) exp -2, yielding straightforward expressions for the variation in the mass, luminosity, and effective temperature. It is noted however, that these expressions are only as good as the initial approximations employed in their derivation.
