1. Exocomets in the β Pictoris system
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Comets have been a source of fascination throughout the history of man. In recent years, advances in technology have opened up for the study of extrasolar objects, among them exocomets. The first exocomets were observed in the β Pictoris system almost 50 years ago and the system has been of interest ever since. LÄS MER
2. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

3. Molns inverkan på satellitdetektion av vegetationsbränder i Sverige
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Results are presented from the 2021 test run of active fire detection using the Visual Infrared Imaging Radiometer Suite (VIIRS) instrument, that is currently onboard the polar satellites Suomi-NPP and NOAA-20. The test is performed by the Swedish Civil Contingencies Agency and the Swedish Meteorological and Hydrological Institute, in cooperation with local fire departments in Sweden. LÄS MER
4. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This Master thesis report contains a complete attitude and orbit control analysis for solar sail spacecraft in the Circular-Restricted-3-Body-Reference frame. The overall goal of the project is to drive one solar sail from the edge of the Earth Sphere of Influence to a vicinity of the sub-Lagrange1 point. LÄS MER
5. Ett varv runt solen är väl en månad - eller är det tusen år? En jämförande intervjustudie om solsystemets himlakroppar med elever i årskurs 6.
Magister-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk professionSammanfattning : Syftet med denna studie är att undersöka hur flera- och multimodala representationsformer kan användas för att ta reda på hur elever förklarar himlakropparnas rörelser. Representationsformerna i denna studie består av skisser och en animerad 3D modell. LÄS MER
