  1. 21. Avoiding the Kessler Effect : An Evaluation of the International Regulation of Space Debris

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Juridiska institutionen

    Författare :Edvin Matton; [2023]
    Nyckelord :space law; space debris; international state responsibility; international state liability;

    Sammanfattning : The mass of space debris in orbit around the Earth is growing and will continue to grow due to more frequent launches of satellites and space debris colliding with other space debris. This could lead to a situation in the future where a part, or all, of the orbit becomes so crowded with space debris that it becomes impossible to launch satellites to that region. LÄS MER

  3. 22. Origin of blue straggler stars in the Milky Way halo

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

    Författare :Adam Brcek; [2023]
    Nyckelord :Blue Straggler; Galactic Halo; Spectroscopic Surveys; Binary Star Evolution; Mass Transfer; Physics and Astronomy;

    Sammanfattning : Blue straggler stars (BSSs) are exotic stellar objects that appear to be younger than the age of the population they come from suggests. They are observed as the extension of the main sequence stars, beyond the turn-off point. LÄS MER

  4. 23. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Henriette Nishimwe; [2023]
    Nyckelord :Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Sammanfattning : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. LÄS MER

  5. 24. Finding stars that are likely to be from accreted satellite galaxies

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

    Författare :Helena Cronstedt; [2023]
    Nyckelord :galaxy mergers; merger debris; velocity space; Physics and Astronomy;

    Sammanfattning : The Milky Way galaxy has through its lifetime merged with several smaller galaxies in its surroundings. Merger events like these play an important role in the formation of galaxies and are therefore of great interest to better our understanding of galaxy formation. LÄS MER

  7. 25. Outer Space Regime and the Issue of Space Debris, An analysis on the Committee on the Peaceful Uses of Outer Space on space debris from 2006 to 2019

    Master-uppsats, Göteborgs universitet/Institutionen för globala studier

    Författare :Paula Nunes Tartari; [2022-03-04]
    Nyckelord :Space Debris; Regime Theory; COPUOS; Outer Space; UNOOSA; Kessler effect; Long-term Sustainability.;

    Sammanfattning : With several actors entering the space scene and the skyrocketed increase in the launches, space exploration has become more complex, so does the challenges related to the threat posed by space debris. To deal with this matter, the United Nations adopted the Space Debris Mitigation Guidelines, and later, the Long-Term Sustainability Guidelines. LÄS MER
