  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. Self-sufficiency of the vineyard of Chteau de la Chaize : Design and Simulation of a grid-connected PV system in South of France

    Master-uppsats, KTH/Energiteknik

    Författare :Noriko Jia Yong Claudine Ly; [2019]
    Nyckelord :;

    Sammanfattning : The task of this master thesis is to evaluate the potential and economic feasibility of a solar photovoltaic project at the Castle Chteau de la Chaize, situated near Lyon in France. The domain of the Chteau de la Chaize aims to be more ecologically responsible, by producing organic wine, using geothermal energy and producing its own electricity, using solar energy. LÄS MER

  3. 3. 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

  4. 4. Dynamics of a high-eccentricity planet in a large planetesimal disc

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Martin Schmidt Montelius; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Clustering of orbital characteristics for distant Solar System objects has been proposed to indicate the presence of a ninth planet. Simulations show that the planets orbit would have to have a mass of 5–10 Solar masses, a semi-major axis of 400–800 AU, an eccentricity of 0.2–0.5 and an inclination of 15–25°. LÄS MER

  5. 5. Formation and Evolution of Protoplanetary Disks

    Master-uppsats, Lunds universitet/Astronomi

    Författare :Johan Appelgren; [2019]
    Nyckelord :protoplanetary disk; protoplanetary disk formation; protoplanetary disk evolution; planet formation; Physics and Astronomy;

    Sammanfattning : A star forms with a surrounding protoplanetary disk after the collapse of a molecular cloud core. Subsequently, over a period of several Myr this protoplanetary disk of dust and gas is accreted onto the host star. We model the formation and evolution of such a protoplanetary disk using a one-dimensional numerical model. LÄS MER
