1. Young stars and circumstellar disks
Sammanfattning : .... LÄS MER
2. Debris disks and the search for life in the universe
Sammanfattning : Circumstellar debris disks are the extrasolar analogues of the asteroid belt and the Kuiper belt. These disks consist of comets and leftover planetesimals that continuously collide to produce copious amounts of circumstellar dust that can be observed as infrared excess or in resolved imaging. LÄS MER
3. 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
4. Gas in Debris Disks
Sammanfattning : .... LÄS MER
5. 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
