| Abstract: |
We present SOHO/SUMER observations of a solar prominence in the hydrogen Lyman series lines and compare the line profiles with the synthetic ones obtained using our 2D prominence modeling. The observations contain the Ly-β, Ly-γ, and Ly-γ lines on 25 May 2005. In order to derive the prominence parameters we used our 2D fine structure models of vertical threads in magnetohydrostatic (MHS) equilibrium. By varying the input model parameters (central temperature, boundary pressure, magnetic field, central column mass and turbulent velocity) we obtained a model having the synthetic Lyman line profiles in good agreement with the observed ones. In this way we are able to determine the structure of the magnetic dip and the thermodynamical parameters in the observed prominence. |
