EXACT 2D MHD MODELLING OF CORONAL LOOPS OBSERVED WITH TRACE AND CDS INCLUDING COMPRESSIBLE FLOW AND HEATING

摘要

We present exact models of coronal loops including heating, which can be compared quantitatively to observational data. The systematic nonlinear separation of variables method used to calculate the equilibria has already been developed in spherical geometry and in Cartesian geometry generalising many known solutions (see [2]). Using a particularly versatile solution class in Cartesian geometry with a large parameter space we are able to calculate models whose loop length, loop shape, plasma density, temperature and velocity profiles are fitted to loops observed with TRACE and with SoHO CDS, while consistent heating profiles are also given.
