Catastrophic cooling in solar coronal loops [Elektronische Ressource] : thermal instability as a road to complex evolution / Daniel Müller

Catastrophic Cooling in Solar Coronal LoopsThermal Instability as a Road to Complex EvolutionDaniel Muller¨The cover illustration shows space-time plots of the modeled temperature distribution along amagnetic loop in the solar corona. The damping length, H , of the energy dissipation in themloop controls the onset of thermal instabilities. Regions of cool, dense plasma result from thesecatastrophic cooling events and propagate towards the footpoints of the loop, seen as dark lanesin the temperature plots. The left and right footpoints of the loop are located atz = 0 Mm andz = 100 Mm, respectively.Dissertation zur Erlangung des Doktorgrades der Fakultat¨ fur¨ Mathematikund Physik der Albert-Ludwigs-Universitat¨Freiburg im BreisgauCatastrophic Cooling in Solar CoronalLoopsThermal Instability as a Road to Complex EvolutionDaniel Muller¨Kiepenheuer Institute for Solar Physics, Freiburg &Institute of Theoretical Astrophysics, OsloOctober 2004Dekan: Prof. Dr. J.
