Abstract
The asymptotic description of low-degree stellar acoustic modes is extended to fourth order in inverse powers of the cyclical frequency. The accuracy of the asymptotic approximation is tested by comparing the predicted values of the eigenfrequencies and the ‘small frequency separations’ with those calculated by solving the full equations governing the adiabatic oscillations of a standard solar model.Keywords
