Abstract

The paper presents the results of an analysis of observations of an eruptive prominence on the MFS and HSFA2 spectrographs of the Ondřejov Observatory (Astronomical Institute, Czech Republic) in the hydrogen, helium, and calcium lines. After spectral processing, the integral radiation fluxes in the lines were determined and the physical parameters of the plasma were calculated theoretically using a model in the absence of local thermodynamic equilibrium. Comparison of the observed and calculated values showed that the observed radiation fluxes in the lines can be explained in a model of stationary gas radiation taking into account the opacity in the spectral lines. To calculate the theoretical fluxes, in some cases, it was necessary to introduce radiation from several layers with different temperatures and heights. The calculated radiation fluxes agree with the observed ones to within 10%. As a result of the simulation, the main parameters of the plasma of the prominence were obtained: temperature, concentration, etc. The values of the radiation fluxes in the spectral lines are evidence of inhomogeneity of the emitting gas, and there may be regions next to each other with temperatures differing by an order of magnitude.
