  1. 1. Hydrodynamic simulations with a radiative surface

    University essay from Institutionen för astronomi

    Keywords : The Sun; Magnetohydrodynamics; radiative transfer;

    Abstract : We solve the equations of radiation hydrodynamics to compute the time evolution toward one-dimensional equilibrium solutions using ageneralized Kramers opacity, κ=κ0 ρa Tb, with adjustable prefactor κ0 and exponents a and b on density ρ and temperature T, respectively. We choose our initial conditions to be isothermal and find that the early time evolution away from the isothermal state is fastest near the height where the optical depth is unity, and is slower both above and below it.
