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. Galactic Dynamics and the spread of Galactic Civilisations
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Abstract The idea of the spread of life through the galaxy is, in most minds, considered science fiction. Yet, scientists argue that most galaxies have had more than enough time for civilisation development and space travel. LÄS MER
3. Europa's Lyman-Alpha Shadow on Jupiter
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Europa is one of the most interesting satellites in the solar system in the search ofextra-terrestrial life, as it harbours an interior water ocean under its icy surface. Watervapour in Europa’s atmosphere has been previously observed, suggesting water plumeeruptions from the surface. LÄS MER
4. High resolution imaging observations of exoplanet host stars
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. LÄS MER
5. Chemical composition of giant planet hosts
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Does the formation of planets give imprints on the chemical composition of the host star? In order to test this theory a differential abundance analysis (i.e. comparing two stars' abundances to each other) was carried out on a few stars with and without known planets, to see if any differences were found.
