Convection and dynamo modeling in protoneutron stars

Résumé

If the Boussinesq approximation performs well in modeling convection in laboratory experiments, it is however unsatisfactory for large natural systems, the lower part of which is compressed by the overlying material. The anelastic approximation enables us to overcome this difficulty by taking into account the mean stratification of the system, while filtering out sound waves for a faster numerical integration. It has been successfully used to study planetary or stellar convection and I will show how it can be further adapted to develop a realistic interior model of a newborn neutron star.
