Synthetic Hydrogen Spectra of Oscillating Prominence Slabs Immersed in the Solar Corona
Original language description
We study the behavior of H alpha and H beta spectral lines and their spectral indicators in an oscillating solar prominence slab surrounded by the solar corona, using an MHD model combined with a 1D radiative transfer code taken in the line of sight perpendicular to the slab. We calculate the time variation of the Doppler shift, half-width, and maximum intensity of the H alpha and H beta spectral lines for different modes of oscillation. We find a non-sinusoidal time dependence of some spectral parameters with time. Because H alpha and H beta spectral indicators have different behavior for different modes, caused by differing optical depths of formation and different plasma parameter variations in time and along the slab, they may be used for prominence seismology, especially to derive the internal velocity field in prominences.
