Energetická rovnováha a teplotní struktura ve slunečních protuberancích / Energy balance and temperature structure in solar prominences

Beck, Dominik January 2021 (has links)
Time evolutions of relaxation of temperature profiles during the cooling of solar prominences are examined based on MALI 1D slab model code written by Petr Heinzel in Fortran. The relaxation is investigated under the assumption of partial redistribution in H, CaII and MgII lines. The effect of conduction and ambipolar diffusion on the slab relaxation is also studied. 1
