Analytical Study of the Structure of Two-Dimensional Magnetostatic Equilibria in the Presence of Gravity

摘要

In order to understand how prominences are supported in the solar corona, we have recently developed several 2D models describing x-invariant equilibrium configurations of a plasma occupying a half-space and submitted to a magnetic field. We report here some results concerning three of these models, which are based on different assumptions about the way matter is spatially distributed. (ERA citation 14:023262)
