Solar plasma theoretical models for STEREO and Solar-B Original Research Article

An overview of several theoretical models addressed to the dynamical and energetic processes in the solar plasmas and coronal magnetic loops, and related to the phenomena of solar flares, CMEs, coronal loop interaction and oscillations is given. The presented models can be organized into two basic groups. The theoretical concept of one group of the models, called as the inductive models, employs the ideas of possible inductive and ponderomotoric interaction between the electric currents confined within the current-carrying magnetic loops moving relative to each other. The models of another group, so-called non-adiabatic MHD models, are applied to describe the MHD response of plasma in the low solar atmosphere to a changing current system of a flaring magnetic tube, which contains an injected beam of fast non-thermal electrons. A detailed information about the structure of coronal loops, their dynamics and global magnetic environment in solar active regions is crucial for all the considered models and it is expected that STEREO and Solar-B observations will be useful for testing and further improvement of these models.
