DIPLOMA THESIS

Title

Modeling of plasma motions in eruptive prominences and coronal mass ejections.

Abstract

The optical spectroscopy of eruptive prominences often indicates very intricate motions of the structures projected to the spectrograph slit. Spectral analysis provides direct information about the structure kinematics. Considering the force fields also reveals the dynamical aspects of the structures. Simpler phenomena can be simulated and compared with archive spectra which often show various peculiarities. Diploma thesis shows four elementary structure models - a cylinder, a cone, an ellipsoid and a spiral. These models can be rotated arbitrarily to the line of sight and their geometric and kinetic parameters can be changed. Typical spectral features are compared with real spectra and kinetic and geometric parameters are deduced.
