  1. 1. Ly-α Dayglow on Uranus : Radiative Transfer Modelling

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jahangir Jazayeri; [2021]
    Keywords : Uranus; Lyman-alpha; Ly-α; resonant scattering; Rayleigh scattering; interplanetary medium; ultraviolet; hydrogen; methane; parameter study; limb brightening; Voyager 2; Ultraviolet Spectrometer;

    Abstract : Uranus is one of the least explored planets in our solar system. Event though the Uranian Ly-α emission has been a subject of study for decades, there is not a consensus on the sources contribution to the total signal. READ MORE

  3. 2. Capture of interstellar objects in the Solar system

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Jonathan Petersson; [2020]
    Keywords : interstellar objects; Physics and Astronomy;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Martin Schmidt Montelius; [2019]
    Keywords : Physics and Astronomy;

    Abstract : 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°. READ MORE

  6. 5. Planet migration in evolving protoplanetary discs

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Linn Eriksson; [2018]
    Keywords : Planets and satellites: formation; Protoplanetary discs: evolution; Planet-disc interactions; Physics and Astronomy;

    Abstract : The rate of migration and accretion onto protoplanets is greatly influenced by the structure of the surrounding protoplanetary disc. This structure changes with time as the disc evolves on a million year timescale, implying that the process of planet formation might look very different depending on when it was initiated. READ MORE
