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. Fractional Habitability comparison of slow rotating Earth-like bodies

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

   Författare :Gustaf Gothefors-Holm; [2023]
   Nyckelord :habitability; General circulation model; climate modelling;

   Sammanfattning : ROCKE-3D is a contemporary Global Circulation Model allowing research into the complex processes behind the climate of planets. Using ROCKE-3D one can construct a model coupling atmosphere, land, and ocean revealing how the climate of a planet evolves over time. LÄS MER

4. 3. Simulations of the Tenuous Upper Atmospheres of Exoplanets

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

   Författare :Lucian Spitzner; [2023]
   Nyckelord :astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

   Sammanfattning : 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. LÄS MER

5. 4. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

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

   Författare :Fredrik Plane; [2022]
   Nyckelord :Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

   Sammanfattning : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. LÄS MER

7. 5. Climate Simulations of an Exoplanet with a Slab Ocean: A 3D Model Intercomparison of various GCMs

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

   Författare :Moa Biserud; [2022]
   Nyckelord :Climate simulations; GCM; ROCKE-3D; Exoplanet; Slab Ocean; Qflux=0;

   Sammanfattning : Three-dimensional (3D) planetary general circulation models (GCMs) have been derived from global climate models used to project 21st century changes in Earth's climate. GCMs are used to address questions regarding the climate-and habitability aspects of terrestrial planets within the solar system and assess the habitability of planets outside of the solar system, so called exoplanets.
