1. N-body simulations of exoplanets and their moons
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
2. Estimating stellar limb darkening using exoplanet transits
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
3. Planning Observations of Terrestrial ExoplanetsAround M Type Stars with CRIRES+
Master-uppsats, Uppsala universitet/Observationell astrofysikSammanfattning : In recent decades, thousands of exoplanets have been discovered. The next step is to characterize theobserved planets in terms of their radii, masses, density, physical conditions and composition of theiratmospheres. LÄS MER
4. Jakten på det försvunna Egypten : En narrativanalys av en konspirationsteori på YouTube
Kandidat-uppsats, Karlstads universitet/Fakulteten för humaniora och samhällsvetenskap (from 2013)Sammanfattning : Det finns en pågående samhällsdebatt om spridning av desinformation på internet och vilka samhällskonsekvenser det kan innebära. På internet, exempelvis YouTube, möjliggörs spridandet av information till en stor publik, utan att någon granskar eller reglerar dess innehåll, vilket i sin tur gör det lättare att sprida desinformation.

5. Searching for Exoplanets in K2 Data
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : The field of extrasolar planets is undoubtedly one of the most exciting and fast-moving in astronomy. Thanks to the Kepler Space Telescope, which has given us the Kepler and K2 missions, we now have thousands of planets to study and thousands more candidates waiting to be confirmed. LÄS MER
