1. The visibility of stellar transients in the Galactic Centre
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. LÄS MER
2. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

3. Effectiveness of the Costa Rican Payments for Ecosystem Services program in mitigation of greenhouse gas emissions: Trends in carbon stocks 2012-2020
Master-uppsats, Lunds universitet/Internationella miljöinstitutetSammanfattning : Payments for ecosystem services (PES), a mechanism of incentives or compensation to landowners for provision of ecosystem services, have grown as a tool for meeting conservation goals. The Costa Rican payments for ecosystem services (PSA) program is one of the best-known examples because of being one of the most established. LÄS MER
4. Properties of the Optical Hot Spots in the Circumstellar Ring of SN 1987A
Master-uppsats, KTH/FysikSammanfattning : The proximity of Supernova 1987A provides a great opportunity to study the aftermath of the impact of the ejecta with the dense clumps (observed as ”hot spots”) located in the equatorial circumstellar ring. This thesis examines the properties of the clumps by using Hubble Space Telescope optical imaging taken with the F625W and F675W broad filters between 1994 and 2022. LÄS MER
5. 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
