16. Giant planet formation around HR8799
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : In the thriving field of exoplanet research new discoveries are made all the time, and while most of the observed systems can be explained with classical planet formation models - some are much harder to explain. When stars form they are often surrounded by the remaining material of the nebulae they formed from. LÄS MER
17. The chemical composition of hot and cold gas giants
Kandidat-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Exoplanet surveys have identified a category of giant planets that orbit very close to their host stars - the so-called hot Jupiters. The origin of such hot Jupiters is a long standing puzzle and has been closely investigated since the first discovery of such planets in 1995. LÄS MER
18. The Giants and their role in Ragnarök
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Observed population of giant planets around evolved stars shows a paucity of planets with semi-major axes below 0.5 au, in contrast to main sequence stars where those planets are present. LÄS MER
