  1. 1. Hybrid Simulations of Solar Wind Plasma Interaction with the Lunar Reiner Gamma Magnetic Anomaly

    University essay from Umeå universitet/Institutionen för fysik

    Author : David Frisk Strömberg; [2023]
    Keywords : ;

    Abstract : The Moon has small scale regions of strong magnetic fields scattered over its surface, known as crustal fields. Coexisting with some of the strongest crustal fields are peculiar markings in the lunar soil, called lunar swirls, which are suggested to be formed by magnetosphere-like interactions between the crustal fields and the solar wind plasma.

  3. 2. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

    University essay from Umeå universitet/Institutionen för fysik

    Author : Gabriella Nordin; [2023]
    Keywords : Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

    Abstract : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. READ MORE

  4. 3. Comprehensive Venus boundaries model : Empirical dependency of boundaries on the upstream conditions

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

    Author : Umberto Rollero; [2023]
    Keywords : Bow shock; Ion Composition Boundary; Venus; Upstream conditions; Solar wind.; Bow shock; Bogshock; Ion Composition Boundary; Venus; Uppströmsförhållanden; Solvind.;

    Abstract : Since Venus is an unmagnetized planet, it doesn’t interact with the solar wind in the same way as planets with an intrinsic magnetic field do. Due to its conductive ionosphere, however, it still possesses an induced magnetosphere. READ MORE

  5. 4. Sporadic-E layers in the polar cap ionosphere : A review on Es occurrence, dynamics and formation theory

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

    Author : Anton Thorell; [2023]
    Keywords : Sporadic-E layers; plasma physics; space physics; arctic geophysics; radar technology; UNIS; Svalbard; EISCAT.; Sporadiska E-skikt; plasmafysik; rymdfysik; arktisk geofysik; radarteknik; UNIS; Svalbard; EISCAT.;

    Abstract : Sporadic-E layers (Es) are layers of metallic ions that appear in the lower E-region of the ionosphere and can last from under one hour to several hours. Es are found at all latitudes, but polar cap Es, and specifically over Svalbard at a latitude of around 78◦ , are the focus of this study. READ MORE

  6. 5. Cusp Aurora Appearing at the Dayside tip of Transpolar Arcs - Dependence on IMF and Dipole Tilt

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

    Author : Cecilie Holmen; Mattias Wang; [2023]
    Keywords : ;

    Abstract : The aurora is a direct consequence of the Earth’s magnetic field interaction withthe solar wind and the interplanetary magnetic field (IMF). In this study, we examine thelocation of the cusp aurora when accompanied by transpolar arcs (TPAs) with the goal to finda dependence on the IMF. READ MORE
