The Thermal Nonequilibrium of Prominences

摘要: We present numerical simulations and analytic theory for the thermal nonequilibrium of solar coronal flux tubes that have a stretched-out, dipped geometry, appropriate prominence/filament. Our indicate if heating in such tube is localized near chromosphere, then condensations appear which undergo continuous cycle formation, motion, destruction, even though all other imposed conditions on loop are purely time independent. show how this nonsteady evolution can be understood terms simple scaling-law theory. The implications observations corona discussed. argue model explain both formation prominence recent their dynamics.
