1. Radio emission from supernovae
Sammanfattning : This thesis presents the modeling of radio and X-ray emissions from supernova (SN) shock fronts and hydrodynamical simulations of SN-circumstellar medium (CSM) interaction. The interaction of SN ejecta with the CSM drives a strong shock wave into the CSM. LÄS MER
2. Measuring the solar atmosphere
Sammanfattning : The new CRISP filter at the Swedish 1-m Solar Telescope provides opportunities for observing the solar atmosphere with unprecedented spatial resolution and cadence. In order to benefit from the high quality of observational data from this instrument, we have developed methods for calibrating and restoring polarized Stokes images, obtained at optical and near infrared wavelengths, taking into account field-of-view variations of the filter properties.

3. Magnetohydrodynamics of Turbulent Accretion Disks and Planet Formation
Sammanfattning : Planets have long been believed to form in disks of gas and dust around youngstars, interacting with their surroundings via a setof complex and highly nonlinear processes. In the core accretion scenario forgiant planet formation dust coagulates first into km-sized icyand rocky planetesimals that further collide, formingprogressively larger solid bodies that eventually give rise to cores of severalEarth masses.
