NONLINEAR PROCESSES IN CORONAL HEATING AND SLOW SOLAR WIND ACCELERATION

[Total: 0    Average: 0/5]

The present work consists of two parts: the first devoted to the study of the heating of the magnetically confined Solar Corona, and the second to the acceleration of the Slow Solar Wind. I have developed a parallel code using MPI. With this I have performed direct 3D reduced MHD simulations, modeling the heating of coronal loops in the solar atmosphere via the tangling of coronal field lines by photospheric footpoints motions within the framework of the ‘Parker scenario’. I carried out long-time simulations with the highest resolutions and longest extent to date. This has allowed me to derive scaling properties with loop length, and ratio of photospheric velocity to coronal Alfv
