1. Circumstellar Debris Disks : Observational Studies of Cold Dust and Gas Emission in Planetary Nurseries
Sammanfattning : Planetary systems form in disks of gas and dust surrounding newborn stars. The young circumstellar environment is characterized by frequent collisions between rocky bodies, leading to a continuous production of small dust grains. LÄS MER
2. Particulate Debris Spreading and Coolability
Sammanfattning : In Nordic design of boiling water reactors, a deep water pool under the reactor vessel is employed for the core melt fragmentation and the long term cooling of decay heated corium debris in case of a severe accident. To assess the effectiveness of such accident management strategy the Risk-Oriented Accident Analysis Methodology has been proposed. LÄS MER
3. Gas in Debris Disks
Sammanfattning : .... LÄS MER
4. Effects of fine woody debris on juvenile brown trout (Salmo trutta) and drifting invertebrates
Sammanfattning : In boreal forest streams, woody debris is an important habitat component. Stream invertebrates and salmonids such as brown trout benefit from in-stream wood. LÄS MER
5. Debris disks from an astronomical and an astrobiological viewpoint
Sammanfattning : In this licentiate thesis, I consider debris disks from an observational, astronomical viewpoint, but also discuss a potential astrobiological application. Debris disks are essentially disks of dust and rocks around main-sequence stars, analogue to the Kuiper- or the asteroid belt in our solar system. LÄS MER
