Understanding the Mg II and Halpha Spectra in a Highly Dynamical Solar Prominence
Original language description
We discuss the possibility to interpret the unreversed single profiles by using a two-dimensional (2D) model of the entire prominence body with specific radiative boundary conditions. We have performed new 2D isothermal-isobaric modeling of both H alphaand Mg II lines and show the ability of such models to account for the line profile variations as observed. However, the Mg II line-center intensities require the model with a temperature increase toward the prominence boundary. We show that even simpleone-dimensional (1D) models with a prominence-to-corona transition region (PCTR) fit the observed Mg II and H alpha lines quite well, while the isothermal-isobaric models (1D or 2D) are inconsistent with simultaneous observations in the Mg II h and k andH alpha lines, meaning that the H alpha line provides a strong additional constraint on the modeling. IRIS far-UV detection of the C II lines in this prominence seems to provide a direct constraint on the PCTR part of the model.
