  • Multiscale Solar Wind Turbulence Properties inside and near Switchbacks Measured by the Parker Solar Probe 

    Martinovic, MM; Klein, KG; Huang, J; Chandran, BDG; Kasper, JC; Lichko, E; Bowen, T; Chen, CHK; Matteini, L; Stevens, M (IOP Publishing, 2021-05)
    The Parker Solar Probe (PSP) routinely observes magnetic field deflections in the solar wind at distances less than 0.3 au from the Sun. These deflections are related to structures commonly called "switchbacks" (SBs), whose ...
