  1. 1. Ett varv runt solen är väl en månad - eller är det tusen år? En jämförande intervjustudie om solsystemets himlakroppar med elever i årskurs 6.

    Magister-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk profession

    Författare :Dino Hajiric; [2020-02-28]
    Nyckelord :Fysik; solsystemet; multimodala representationsformer; omloppsbanor; dag och natt; omloppstider.;

    Sammanfattning : Syftet med denna studie är att undersöka hur flera- och multimodala representationsformerkan användas för att ta reda på hur elever förklarar himlakropparnas rörelser. Representationsformerna i denna studie består av skisser och en animerad 3D modell. LÄS MER

  2. 2. 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

  3. 3. Space Surveillance and Tracking Tool: Implementation and Test of New Methods​

    Master-uppsats, KTH/Rymdteknik

    Författare :Giovanni Cirillo; [2019]
    Nyckelord :;

    Sammanfattning : In March 2019 the number of artificial objects bigger than 1 mm in orbit around the Earth is estimated to be more than 170 millions. Only a small fraction of them (0.03%) is catalogued. An impact of an operational satellite with one of these debris can damage the satellite and undermine its mission. LÄS MER

  4. 4. Hunting for Planet Nine by its perturbations on the Main Asteroid Belt

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Albin Jonsson; [2019]
    Nyckelord :Planet Nine; Main Asteroid Belt; Perturbations; evection resonance; libration; Physics and Astronomy;

    Sammanfattning : In recent years, scientists have found unconfirmed evidence for a ninth planet in the solar system at a very wide orbit. The parameters for this planet are poorly constrained. Current estimates mostly come from the effect the planet has on trans-neptunian objects. LÄS MER

  5. 5. Can tidal interactions produce MGC1?

    Master-uppsats, Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Författare :Eric Andersson; [2018]
    Nyckelord :globular cluster; MGC1; Andromeda; M31; galaxy; dwarf galaxy; tidal interactions; Physics and Astronomy;

    Sammanfattning : The globular cluster population of large spiral galaxies can be divided into two populations: one population which formed in-situ and one which has been assembled through capture of clusters that have been tidally stripped away from other galaxies during close encounters or mergers. In this work, I focus on the globular cluster MGC1, which is orbiting the M31 galaxy. LÄS MER
