Validity of the Boussinesq approximation in the magneto-rotational instability (MRI)Â
Abstract
The Boussinesq approximation is frecuently used in the magneto-rotational instability. In this paper we analize this approximation in the hydrostatic and the magnetohydrodynamic with diferential rotation cases. We study the validity of the approximation and the conditions on the magnetic induction. FULL TEXT IN SPANISH
