1. Starshades: Geoengineering Solutions and Technosignatures in Direct Imaging Phase Curves
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : The stellar luminosity increases as a star evolves which inevitably yields a higher temperature on planets in orbit around the star. It is reasonable to assume that intelligent civilizations would tackle this issue through installing artificial structures that can alter the radiation received by the planet. LÄS MER
2. Climate Simulations of an Exoplanet with a Slab Ocean: A 3D Model Intercomparison of various GCMs
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : 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.

3. Assessing the relationship between hypoxia and life on Earth, and implications for the search for habitable exoplanets
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Atmospheric oxygen at the level of present-day Earth (21%) is generally regarded as permissive for the development and survival of complex multicellular life, such as animals. The hypothesis that oxic conditions are conducive for multicellular life has subsequently been applied to the search for life elsewhere in the universe, with planets exhibiting atmospheric oxygen of a similar level to Earth being considered as candidates for habitability.

4. Post-Main Sequence Habitability for Outer Solar System Moons
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The search for extra-terrestrial life is guided by the classification of promising candidate worlds. In this classification the habitable zone acts as a measure for the perceived habitability of a circumstellar body. Habitable zone definitions vary between using a conservative and an optimistic limit. LÄS MER
5. Have Radial Velocity Surveys Missed Any Planets?
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionenSammanfattning : The project was aimed at numerically assessing exoplanetary systems to distinguish their capabilities of hosting additional planets. The shortcomings of the radial velocity method sometimes causes hindrance in the detection of terrestrial planets. LÄS MER
