A Unified Model of Solar Prominence Formation

Several mechanisms have been proposed to account for the formation of solar prominences or filaments, among which direct injection and evaporation-condensation models are two most popular ones. In model, cold plasma is ejected from chromosphere into corona along magnetic field lines; chromospheric heated over a million degrees evaporated corona, where accumulated finally reaches thermal instability non-equilibrium so as condensate prominences. this paper, we try unify mechanisms: The essence filament localized heating in chromosphere. If happens lower chromosphere, enhanced gas pressure pushes upper move up such process manifested model. local degrees, corona. Later, condensates form prominence. Such With radiative hydrodynamic simulations confirmed that widely accepted can really be unified single framework. A particular case also found both processes occur together.
