1. 1. Wavelength-dependent limb darkeningin the analysis oftransit spectroscopy of exoplanets

   L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Alberto García Ribas; [2023]
   Nyckelord :;

   Sammanfattning : Limb darkening, an optical effect characteristic of stars, where the limb (edge) seemsto be darker than the centre of the stellar body; plays an important role in our under-standing of exoplanetary transits, as it is fundamental for developing light curve modelsthat can help to undercover extrasolar companions. To recover atmospheric featuresfrom exoplanets, a principal component analysis method is typically used. LÄS MER

3. 2. 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
