  1. 1. Study of oblique whistler waves in coronal mass ejections observed by Solar Orbiter

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Sofia Lennerstrand; [2023]
    Keywords : Oblique whistler waves; Solar physics; Solar Orbiter;

    Abstract : In this paper a search routine in MATLAB was developed in order to find and analyze oblique whistler waves in the data from the ESA and NASA spacecraft Solar Orbiter. Oblique whistler waves are a type of plasma wave which propagate at an angle with respect to the background magnetic field. READ MORE

  3. 2. Čerenkov emission of whistler waves by electron holes

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Nedjma Ouahioune; [2021]

    Abstract : Electron holes are positively charged nonlinear structures in which trapped electrons are supported by a positive electrostatic potential. These structure are regularly observed in space and laboratory plasmas by means of diverging bipolar electric field signatures. READ MORE

  4. 3. Instrument characterization of the THEMIS EFI

    University essay from Institutionen för fysik och astronomi; Institutet för rymdfysik, Uppsalaavdelningen

    Author : Sara Lindgren; [2011]
    Keywords : THEMIS EFI; transfer function; sheath impedance;

    Abstract : In March 2007 five satellites were launched as part of the NASA mission THEMIS. The aim of the mission is to answer the unknown questions regarding the onset of substorms. THEMIS data has also been used within other research fields. READ MORE

  5. 4. A Survey of Low-Frequency Plasma Waves in the Magnetosphere of Saturn

    University essay from KTH/Rymd- och plasmafysik

    Author : Markus Landgren; [2008]
    Keywords : ;

    Abstract : The Cassini mission to Saturn carries a wide variety of instruments to investigate Saturn and its surroundings. Since Cassini is an orbiter, the spatial coverage of this mission far exceeds the few flybys made by earlier spacecraft. READ MORE

  6. 5. Spatial correlation between lightning strikes and whistler observations

    University essay from KTH/Rymd- och plasmafysik

    Author : Jonas Öster; [2008]
    Keywords : ;

    Abstract : A whistler wave is a Very Low frequency (VLF) trace that obtains its characteristics from dispersive propagation in the magnetosphere. Field-aligned ducts of enhanced plasma density ensure the propagation from one hemisphere to the other. READ MORE
