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. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

3. Simulations of the Tenuous Upper Atmospheres of Exoplanets
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : 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
4. AI-paradoxen
Kandidat-uppsats, Uppsala universitet/Filosofiska institutionenSammanfattning : Derek Parfit är kanske en av vår tids mest kända moralfilosofer. Parfit inleder sin första bok Reasons and Persons med att ställa frågan: vad har vi mest skäl att göra? Hans fråga berör vad som egentligen har betydelse, en fråga som han fortsätter att beröra i sin andra bok On What Matters. LÄS MER
5. Evolution and Differentiation of Large Icy Moons
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Purpose: In preparation of several future missions with the objective to research the large icy moons of the Solar System, it is necessary to have a cohesive understanding of the conditions that might lead to the formation of liquid oceans in these moons. The purpose of this work is to create a numerical model for simulating the temperature evolution of the cores of large icy moons. LÄS MER
