Dynamics of a solar prominence simulated with MURaM — •Lisa-Marie Zessner, Robert Cameron, Sami Solanki, and Damien Przybylski — Max Planck Institute for Solar System Research, Göttingen, Germany

Solar prominences are cool and dense plasma clouds suspended in the hot solar corona, supported by the solar magnetic field. These complex and dynamic structures exhibit various types of mass motion and exchange mass with the solar surface and the surrounding atmosphere. Understanding the nature and origin of these dynamics is an important part of solar prominence research.

We use the 3D radiative magnetohydrodynamic code MURaM to simulate the formation and properties of solar prominences in a dipped magnetic arcade configuration. The prominence formation process starts by injection of cool and dense plasma seeds from the chromosphere into the corona. These injections are accompanied by photospheric flux cancellation and reconfigurations of the magnetic field above the surface. The subsequent mass build-up of the prominence is a combination of these continued cool injections and condensation of hot plasma. The resulting prominence structure is dynamic, featuring differently oriented structures and drainage to the surface. In this talk, we present the evolution of individual injection events that feed the prominence, as well as the motion and dynamics of the prominence plasma.
