1. N-body simulations of exoplanets and their moons
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. READ MORE

2. Estimating stellar limb darkening using exoplanet transits
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. READ MORE

3. Forming wide-orbit planets via pebble accretion
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. READ MORE

4. Simulations of the Tenuous Upper Atmospheres of Exoplanets
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

5. Search for transiting exoplanets in globular clusters
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. READ MORE
