Steady flows in solar magnetic structures-A class of exact MHD solutions

A. De Ville, E. R. Priest

Research output: Contribution to journalArticlepeer-review


A class of exact solutions to the steady, two-dimensional magnetohydrodynamic equations in a cylindrical geometry is presented. These may model both closed and open magnetic structures found in the solar atmosphere. For closed structures, it is found that increasing the flow speed causes the summit of the arcade of closed magnetic fieldlines to rise. Parameter ranges also exist where the solution has regions of open and closed field, and so the solutions may be relevant for modelling flows in solar magnetic structures such as coronal streamers, X-ray bright points, coronal plumes and coronal holes.
