Description
We study 3D radiative transfer of solar filaments. When observed on the solar disk, filaments are in absorption and can be seen as dark stripes against the bright solar surface. When seen above the solar limb (also called solar prominences) they are observed in emission and can be recognized as bright phenomena against the dark background of space.
In this study, we attempt to create a continuum radiative transfer code, based on the Monte Carlo algorithm, to simulate the interaction of the solar photons with solar filaments. For this, we modify the existing SKIRT code. SKIRT, or ‘Stellar Kinematics including Radiative Transfer’ is mostly used for simulating the radiative transfer in dusty galaxies. We extend the code by including the wavelenth-dependent absorption and emission of photons in the optically thick H-α and Ly-α wavelengths. The ultimate aim is to compare observations of prominence oscillations with the numercial simulations of those.
