  1. 1. Potentiella nedslagskratrar i Sverige med fokus på Östersjön och östkusten

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Jonna Johansson; [2020]
    Nyckelord :nedslagsstrukturer; potentiella nedslagsstrukturer; Östersjön; östkusten; Gotland; Earth and Environmental Sciences;

    Sammanfattning : Impact structures are one of the most common geologic structures in our solar system, but relatively few impact structures have been found on Earth. There are many reported potential impact structures, but few have been investigated or confirmed. LÄS MER

  2. 2. Galactic Dynamics and the spread of Galactic Civilisations

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Markus Strickert; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. 3. Capture of interstellar objects in the Solar system

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Jonathan Petersson; [2020]
    Nyckelord :interstellar objects; Physics and Astronomy;

    Sammanfattning : Research on InterStellar Objects (ISOs) has been done for several decades, however, the first observed ISO in the Solar system was only recently discovered in 2017. It was named 1I/'Oumuamua and was only passing though the Solar system, but this may not be the case for all objects of its kind. LÄS MER

  4. 4. How did Jupiter form?

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Calle Ahlgren; [2019]
    Nyckelord :Planet formation; Planet migration; Physics and Astronomy;

    Sammanfattning : Two relatively new concepts in planetary science are planetary migration; wherein the planets migrate through the protoplanetary disk as they form, and pebble accretion; wherein the planetesimals which become terrestrial planets and giant planet cores grow through the accretion of small pebbles. Planetary migration has become a generally accepted concept but there is still much to be learned even about how it affected the formation of our own solar system. LÄS MER

  5. 5. The Solar System Around a Binary Star

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Jesper Nielsen; [2019]
    Nyckelord :planetary system stability; binary star; Physics and Astronomy;

    Sammanfattning : The observations of circumbinary planets have confirmed that these can in fact be stable. While previous studies on circumbinary planets have been done, not many have been made on systems containing multiple circumbinary planets on eccentric orbits. LÄS MER
