The numerical simulation of non-linear non-radial stellar pulsations: a conservative formulation of gravity

The simulation of finite amplitude stellar pulsations and the theoretical determination of the final fate of violently unstable stellar models require the complete consideration of the mechanics and thermodynamics of a star. In particular, non-linear effects need to be taken into account. Numerical methods for the study of non-linear pulsations are available so far only for spherically symmetric r...
