Magnetohydrodynamics of rotating compact stars with spectral methods: description of the algorithm and tests

Résumé

A flexible spectral code for the study of general relativistic magnetohydrodynamics is presented. Aiming at investigating the physics of slowly rotating magnetized compact stars, this new code makes use of various physically motivated approximations. Among them, the relativistic anelastic approximation is a key ingredient of the current version of the code. In this paper, we mainly outline the method, putting emphasis on algorithmic techniques that enable to benefit as much as possible from the non-dissipative character of spectral methods, showing also a potential astrophysical application and providing a few illustrative tests.
