PPT-Coronal Prominence Cavities: Magnetism and Dynamics

Sarah Gibson Giuliana de Toma Therese Kucera Kathy Reeves Donald Schmit and Alphonse Sterling Abstract Coronal mass ejections CMEs and associated prominence eruptions are spectacular manifestations of the Suns magnetic energy  Elliptical regions of rarefied density or cavities are commonly observed surrounding coronal prominences both quiescent and erupting  The prominencecavity system is structured by magnetism providing clues to to the processes that destabilize these . The genesis of solar coronal mass ejections CMEs is both an intellectually intriguing fundamental unsolved problem in plasma astrophysics and a societally relevant subject critical to space weather prediction and mitigation Understanding the preerup in Solar Disk Images .
