  2. 1. High-speed jets and related phenomena at Earth's bow shock and magnetosheath

    Author : Savvas Raptis; Tomas Karlsson; Drew Turner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetosheath; solar wind; bow shock; plasma; collisionless shock; Physics; Fysik;

    Abstract : Magnetosheath high-speed jets are transient and localized dynamic pressure enhancements downstream of Earth’s bow shock. Their formation has been associated with several mechanisms, including solar transient events and the dynamical evolution of the bow shock. READ MORE

  4. 2. Electron energization in near-Earth space : Studies of kinetic scales using multi-spacecraft data

    Author : Elin Eriksson; Andris Vaivads; Masahiro Hoshino; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic reconnection; electron acceleration; electron heating; magnetosheath; magnetotail; magnetic nulls; Cluster; Magnetospheric MultiScale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Plasma, a gas of charged particles exhibiting collective behavior, is everywhere in the Universe. The heating of plasma to millions of degrees and acceleration of charged particles to very high energies has been observed in many astrophysical environments. How and where the heating and acceleration occur is in many cases unclear. READ MORE

  5. 3. Solar wind interaction with the terrestrial magnetopause

    Author : Lars-Göran Westerberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Magnetic reconnection plays an important role in the transfer of mass, energy and momentum from the solar wind to the terrestrial magnetosphere. The earliest contributions to the theory of magnetic reconnection dates from the beginning of the 1930's. READ MORE

  6. 4. Structures and processes in the Mercury magnetosphere

    Author : Elisabet Liljeblad; Tomas Karlsson; Anita Kullen; Haje Korth; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mercury; MESSENGER; magnetosphere; processes; structures; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The mechanisms involved in the transfer of mass and energy from the solar wind to any planetary magnetosphere is considered an important topic in space physics. With the use of the Mercury spacecraft MESSENGER's data, it has been possible to study these processes in an environment different, yet similar, to Earth's. READ MORE

  7. 5. O+ heating, outflow and escape in the high altitude cusp and mantle

    Author : Rikard Slapak; Andrew Yau; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Abstract : The Earth and its atmosphere are embedded in the magnetosphere, a region in space dominated by the geomagnetic field, shielding our planet as it acts to deflect the energetic solar wind. Even though the atmosphere is protected from direct interaction with the solar wind it is indirectly affected by significant magnetosphere-solar wind interaction processes, causing constituents of the upper atmosphere to flow up into the magnetosphere.
