  4. 8. Formation of Pebble-Pile Planetesimals and the Interior Structure of Comets

    Författare :Karl Wahlberg Jansson; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; planets and satellites: formation; minor planets; asteroids: general; comets: general;

    Sammanfattning : Planets form in protoplanetary discs of gas, dust and ice around newborn stars. In the Solar System, not only planets are found as a result from the time of planet formation, but also remnant planetesimals in the form of asteroids, Kuiper belt objects and comets. Recent observations, e.g. LÄS MER

  5. 9. A Study of Jupiter Trojans

    Författare :Ola Karlsson; Claes-Ingvar Lagerkvist; Karri Muinonen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Jupiter Trojans; Trojan asteroids; Minor planets; Solar system;

    Sammanfattning : Jupiter Trojan asteroid dynamics have been studied for a long time but it is only within the last decades that the known population has become large enough to make other studies meaningful. In four articles I have been scratching the surface of the unknown Trojan knowledge space. LÄS MER

  7. 10. Disentangling the Early History of the Solar System

    Författare :Simona Pirani; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; planets and satellites: formation; planets and satellites: dynamical evolution and stability; Kuiper belt: general;

    Sammanfattning : Giant planets form out of a disc of gas and dust – called protoplanetary disc -- that surrounded the protosun at the time of its formation. While the cores of giant planets were growing via planetesimal and pebble accretion, they started to interact with the gas in the protoplanetary disc. LÄS MER
