  2. 6. Numerical modelling of ENAs from stellar wind interactions

    Author : Andreas Ekenbäck; Mats Holmström; Michael R. Collier; Institutet för rymdfysik (IRF); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space physics; Space technology; Astrophysics; Space engineering; Rymdteknik;

    Abstract : Energetic neutral atoms (ENAs) are produced whenever a stellar wind encounters a neutral atmosphere. If a stellar wind proton comes sufficiently close to a neutral a charge-exchange reaction may take place, transforming the proton into an ENA. READ MORE

  4. 7. Pre-biotic molecules and dynamics in the ionosphere of Titan : a space weather station perspective

    Author : Oleg Shebanits; Jan-Erik Docent; Ingo Müller-Wodarg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Saturn; Titan; Ionosphere; Langmuir Probe; Space and Plasma Physics; Rymd- och plasmafysik;

    Abstract : Saturn’s largest moon Titan (2575 km radius) is the second largest in the Solar system. Titan is the only known moon with a fully developed nitrogen-rich atmosphere with ionosphere extending to ~2000 km altitude, hosting complex organic chemistry. READ MORE

  5. 8. Development and simulated observations of the Jovian Neutrals Analyzer

    Author : Angèle Pontoni; Manabu Shimoyama; Mats Holmström; Ove Andersson; Andrew Yau; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; space instrumentation; space physics; Ganymede; Jupiter; fysik; Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Abstract : This thesis deals with the development of the Jovian Neutrals Analyzer (JNA) for the Jupiter ICy moons Explorer (JUICE) mission to Jupiter, planned to launch in 2023. Jupiter, the largest planet in the Solar System, orbits the Sun at five times the distance from the Earth to the Sun, accompanied by dozens of moons, rings, and the largest object in the SolarSystem: the Jovian magnetosphere.

  6. 9. Solar Wind Proton Interactions with Lunar Magnetic Anomalies and Regolith

    Author : Charles Lue; Yoshifumi Futaana; Stas Barabash; Urs Mall; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; the Moon; solar wind; magnetic anomalies; regolith; space physics; plasma physics; particle-surface interactions; mini-magnetospheres; energetic neutral atoms; Space Physics; rymdfysik;

    Abstract : The lunar space environment is shaped by the interaction between the Moon and the solar wind. In the present thesis, we investigate two aspects of this interaction, namely the interaction between solar wind protons and lunar crustal magnetic anomalies, and the interaction between solar wind protons and lunar regolith.

  7. 10. Titan’s ionosphere and dust : – as seen by a space weather station

    Author : Oleg Shebanits; Jan-Erik Wahlund; Wolf Dietrich Geppert; Olle Björneholm; Erik Vigren; Cesar Bertucci; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titan; Cassini; Ionosphere; Dusty plasma; Ion-ion plasma; Langmuir probe; aerosols; tholins; Space and Plasma Physics; Rymd- och plasmafysik;

    Abstract : Titan, the largest moon of Saturn, is the only known moon with a fully developed nitrogen-rich atmosphere, its ionosphere is detectable as high as 2200 km above its surface and hosts complex organic chemistry. Titan’s atmosphere and ionosphere has striking similarities to current theories of these regions around Earth 3.5 billion years ago. READ MORE
