Scientific paper

A Henyey relaxation method with fourth-order truncation errors and accurate error control is described for modeling stellar evolutionary sequences. The model includes four interior equations of a nonrotating, quasi-static star and four boundary conditions. The equations are treated as a system of nonlinear algebraic equations solved by a Newton-Raphson procedure. The higher order truncation error is obtained by using the Runge-Kutta-Fehlberg method (1970) to generate fourth- and fifth-order approximations. The truncation error is then the difference between the approximations, and has proven useful for avoiding the appearance of an excessive number of shells in computations.
