Scientific paper

A method for computing stellar evolutionary sequences is described. The well-known 'Henyey' and 'integration' methods are each special cases of the present one, which should combine some of the best features of each of the older methods. The procedure is characterized by having multiple fitting points, rather than one as in the usual fitting point scheme. The multiple fitting points take on the role of the Henyey shells in the iterative solution of the differential equations. It turns out that the procedure was developed eariler by Reiz and Petersen in unpublished work. A similar method has been briefly described by Eggleton (1968).
