Scientific paper

Collocation with piecewise continuous polynomials is studied for use in the numerical modelling of stellar evolution. Accuracy and convergence of the method are demonstrated for a five solar mass star with a convective core. Collocation should be studied further since it is likely to lead to significant gains in computational efficiency for the construction of stellar models.
