New approach for inclusion of the effect of gravity in magnetohydrostatic equilibrium in solar coronal arcades

Abstract

The study presents a novel approach for the inclusion of the effect of gravity in the magnetohydrostatic equilibrium in coronal arcades, in which the magnetic lines of force are unaffected whereas the pressure isobars are distorted owing to the inclusion of the effect of gravity. In the earlier approach, it was an essential requirement to represent plasma by an ideal gas, whereas the present approach remains unaffected whether plasma is represented by an ideal gas or not
