1. 1. Estimating stellar limb darkening using exoplanet transits

   Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Sora Ishida; [2023]
   Nyckelord :Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

   Sammanfattning : 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. 2. Stars Eating Planets

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :John Wimarsson; [2020]
   Nyckelord :Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

   Sammanfattning : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. LÄS MER
