Granada Oscillation Code (GraCo)

Andres Moya

Abstract. Following the Henyey method for the resolution of a system of differential equations prescribed in Unno et al. 1989, the GraCo oscillation code obtain non-radial, adiabatic and non-adiabatic, numerical solutions. The usual source of equilibrium models is CESAM. Equilibrium models coming from the code of A.Claret or the code of J. McDonald can be also used. Different mechanical outer boundary conditions can be chosen, and also the eulerian or lagrangian variations of the pressure as eigenfunction. An additional characteristic of the code is the inclusion of the atmosphere-pulsation interaction following Dupret et al. 2003.
