Diagnosing the Prominence-Cavity Connection
Abstract
Prominences are regions of cool, dense plasma which are suspended above the solar limb within the much hotter and more rarefied solar corona. The coronal environment surrounding the prominence is often observed as an elliptical region of reduced density (compared to the ambient corona) known as a cavity. The fundamental problems in prominence physics are the magnetic support of condensed plasma and the mass-source of those condensations. We use the SDO/AIA dataset to probe the correlated dynamics in between the cool prominence and the coronal cavity. These dynamics are explained through the 1D modeling of the radiative instability. The magnetic field inferred from these dynamics is also compared to the 3D MHD models of prominence support. Through this joint approach, the dynamic nature of the prominence system is brought into sharp focus for the first time.
