  1. 1. Archaeologic inspection of the Milky Way using vibrations of a fossil : Seismic, spectroscopic and kinematic characterization of a binary metal-poor Halo star

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Amanda Byström; [2020]
    Keywords : Milky Way; Halo; galactic archaeology; asteroseismology; binary star; CEMP stars; CEMP-r s stars; stellar age; stellar mass; chemical abundance pattern; Gaia-Enceladus; Gaia-Sausage; Sequoia; spectroscopy; metal-poor;

    Abstract : The Milky Way has undergone several mergers with other galaxies during its lifetime. The mergers have been identified via stellar debris in the Halo of the Milky Way. The practice of mapping these mergers is called galactic archaeology. To perform this archaeologic inspection, three stellar features must be mapped: chemistry, kinematics and age. READ MORE

  2. 2. Investigating Adaptive Trajectories to Explore Water Plumes on Icy Moons

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

    Author : Marcus Ackland; [2018]
    Keywords : ;

    Abstract : This thesis investigates different means of introducing autonomy intodesigning spacecraft trajectories by surveying four different adaptivetrajectories. This is done using established algorithms within pathplanning and robotics, implementing trajectories based on splines andgreedy algorithms. READ MORE

  3. 3. Investigation of the electron density close to the rings of Saturn and Prediction of the F-ring plasma characteristics

    University essay from Uppsala universitet/Institutionen för fysik och astronomiUppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : George Xystouris; [2016]
    Keywords : ;

    Abstract : Saturn has the second strongest magnetic field among the planets of the solar system, creating the second biggest magnetosphere, after Jupiter. The magnetosphere is similar to Earth's, as both of them are created by a dipole magnetic field, produced by a planetary dynamo. Despite the similarities, they have some major differences. READ MORE

  4. 4. Plasma Structures at the Enceladus Plume

    University essay from Uppsala universitet/Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenRymd- och plasmafysik

    Author : Ilka A.D. Engelhardt; [2013]
    Keywords : Enceladus; Plasma Density; Fine Structure;

    Abstract : Cassini-RPWS high resolution (20 Hz) Langmuir probe data was analyzed to find the source of fast variations in the electron density especially in the Enceladus plume region. The spatial scale on the variations is between 1 and 10 km in size. READ MORE
