  1. 1. N-body simulations of exoplanets and their moons

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

    Författare :Lydia Schollmeier; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. LÄS MER

  3. 2. Investigation of Antenna Radomes in Low Earth Orbits

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Mathias Manohar Gren; [2023]
    Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Sammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  4. 3. System Architecture for Lunar Oxygen Production from Regolith Using a Model-Based System Engineering Approach

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Kim Lamboley; [2022]
    Nyckelord :ISRU; MBSE; Exploration; Moon; Space; Resources; Regolith; Pyrolysis; Oxygen; Production; ISRU; MBSE; Utforskning; Månen; Rymd; Resurser; Regolit; Pyrolys; Syre; Produktion;

    Sammanfattning : Technologies for production and utilisation of space resources are still in the early phases of development. Oxygen in particular is an interesting resource for both life-support and as propellant, and can be widely found on the lunar surface embedded in metallic oxides in the lunar soil. LÄS MER

  5. 4. Post-Main Sequence Habitability for Outer Solar System Moons

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Viktor Sparrman; [2022]
    Nyckelord :Habitability; Habitable Zone; Greenhouse Effect; Outer moons; Red Giant Branch; Horizontal Branch; Asymptotic Giant Branch; solar evolution;

    Sammanfattning : 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

  7. 5. Den tredje Adam : En kvalitativ textanalys om Familjefederationens teologiska syn på frälsningen utifrån ett genusperspektiv

    Uppsats för yrkesexamina på avancerad nivå, Jönköping University/Högskolan för lärande och kommunikation

    Författare :Joakim Choi; [2021]
    Nyckelord :Familjefederationen; Moonrörelsen; Moon; teologi; frälsning; genus; genusperspektiv; Hirdman; religionsvetenskap; nyreligösa rörelser; nyreligiositet; Korea;

    Sammanfattning : After the end of World War II, so-called New Religious Movements (NRM) emerged as branches of the traditional religions. These NRM’s are characterized by new ways of forming belief systems and has traditions that are different from the conventional religions. LÄS MER
