6. Theoretical Studies of Binaries in Astrophysics
Sammanfattning : This thesis introduces and summarizes four papers dealing with computer simulations of astrophysical processes involving binaries. The first part gives the rational and theoretical background to these papers. In paper I and II a statistical approach to studying eclipsing binaries is described. LÄS MER
7. High-contrast imaging of low-mass companions and debris disks
Sammanfattning : The search for exoplanets, i.e., planets orbiting other stars than the Sun, is a relatively new research field, but has already established itself as one of the most prolific and intriguing areas of astronomy. LÄS MER
8. Observing Lyman alpha emitters - How does Lyman alpha escape from galaxies?
Sammanfattning : The Lyman alpha (Lyα) emission line has grown to become one of the most successful tools for finding galaxies at high redshift. At redshifts corresponding to the early cosmic times of reionization and primeval galaxy formation, the wavelength of Lyα is still accessible with ground-based facilities. LÄS MER
