  1. 16. Kinetic Modeling of the Solar Wind Plasma Interaction with the Moon

    Författare :Shahab Fatemi; Geraint Jones; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : The main purpose of this research is to understand various aspects of the solar wind plasma interaction with the Earth's Moon by the means of kinetic computer simulations. The Moon is essentially a non-conducting object, that has a tenuous atmosphere and no global magnetic field. LÄS MER

  3. 17. Plasma and Dust around Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

    Författare :Ilka. A. D. Engelhardt; Anders Eriksson; Ingrid Mann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : Saturn's moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. LÄS MER

  4. 18. Plasma and Dust at Saturn's Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

  5. 19. Modeling the Lunar plasma wake

    Författare :Shahab Fatemi; Bengt Eliasson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : This thesis discusses the solar wind interaction with the Moon and the formation of the lunar plasma wake from a kinetic perspective. The Moon is essentially a non-conducting body which has a tenuous atmosphere and no global magnetic fields. The solar wind plasma impacts directly the lunar day-side and is absorbed by the lunar surface. LÄS MER

  7. 20. Celestial Cycles : Astronomical Concepts of Regeneration in the Ancient Egyptian Coffin Texts

    Författare :Patrik Wallin; Katja Goebs; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Archaeology; Ancient Egypt; Coffin Texts; Astronomy; Middle Kingdom; calendars; time; Arkeologi; Archaeology subjects; Arkeologiämnen; Egyptology; Egyptologi; Informatics; computer and systems science;

    Sammanfattning : This study analyzes the astronomical references found in the ancient Egyptian Coffin Texts. Chapter i presents the aim and method of this study as well as describing the primary sources and previous research. Chapter 2 deals with the conceptual background for the three cycles, as related to the year, month and the day as units of time. LÄS MER
