1. Ly-α Dayglow on Uranus : Radiative Transfer Modelling
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Uranus is one of the least explored planets in our solar system. Event though the Uranian Ly-α emission has been a subject of study for decades, there is not a consensus on the sources contribution to the total signal. LÄS MER
2. Capture of interstellar objects in the Solar system
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Research on InterStellar Objects (ISOs) has been done for several decades, however, the first observed ISO in the Solar system was only recently discovered in 2017. It was named 1I/'Oumuamua and was only passing though the Solar system, but this may not be the case for all objects of its kind. LÄS MER
3. Hunting for Planet Nine by its perturbations on the Main Asteroid Belt
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : In recent years, scientists have found unconfirmed evidence for a ninth planet in the solar system at a very wide orbit. The parameters for this planet are poorly constrained. Current estimates mostly come from the effect the planet has on trans-neptunian objects. LÄS MER
4. Dynamics of a high-eccentricity planet in a large planetesimal disc
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Clustering of orbital characteristics for distant Solar System objects has been proposed to indicate the presence of a ninth planet. Simulations show that the planets orbit would have to have a mass of 5–10 Solar masses, a semi-major axis of 400–800 AU, an eccentricity of 0.2–0.5 and an inclination of 15–25°. LÄS MER
5. Planet migration in evolving protoplanetary discs
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : The rate of migration and accretion onto protoplanets is greatly influenced by the structure of the surrounding protoplanetary disc. This structure changes with time as the disc evolves on a million year timescale, implying that the process of planet formation might look very different depending on when it was initiated. LÄS MER
