1. The Dynamics of Star Cluster Formation
Sammanfattning : How do star clusters form? We care, since these are the birth sites of most stars, perhaps including our own Sun. There are a great variety of different theoretical models of cluster formation and our main goal in this thesis is to examine the implications of these for the dynamical evolution of a cluster's stellar population, including the ejected stars.

2. Molecular gas and ionizing radiation in star-forming galaxies
Sammanfattning : In cosmic history, some of the major changes such as reionization were driven by baryons (i.e. the stars and gas in galaxies), despite the fact that they contribute only few percent to the total mass-energy budget in the Universe. LÄS MER
3. Turbulence-Assisted Planetary Growth : Hydrodynamical Simulations of Accretion Disks and Planet Formation
Sammanfattning : The current paradigm in planet formation theory is developed around a hierarquical growth of solid bodies, from interstellar dust grains to rocky planetary cores. A particularly difficult phase in the process is the growth from meter-size boulders to planetary embryos of the size of our Moon or Mars. LÄS MER
4. Th Dynamics of Star Cluster Formation
Sammanfattning : A major question in astrophysics is how star clusters form. These objects are important, since they are the birth sites of most stars, perhaps including our own Sun. LÄS MER
5. Dynamics and Erosion of Solids in Protoplanetary Disks
Sammanfattning : Protoplanetary disks are the natural by-product of star formation and the sites of planet formation. Initially, they are composed of the gas and small solids they inherit from the molecular cloud they form in. The interactions between this material is complex and understanding their details is key for a complete picture of planet formation. LÄS MER
