Near-Sun Switchbacks Show Statistical Signatures of Solar Activity
Sneha Pandit, Thierry Dudok de Wit, Clara Froment +3
The large amplitude, Alfvénic deflections in the solar wind, called magnetic switchbacks, are a ubiquitous feature of the inner heliosphere, yet their origin and variability remain…
Properties of Magnetic Switchbacks in the Near-Sun Solar Wind
Samuel T. Badman, Naïs Fargette, Lorenzo Matteini +24
Magnetic switchbacks are fluctuations in the solar wind in which the interplanetary magnetic field sharply deflects away from its background direction so as to create folds in magn…
Tracing magnetic switchbacks to their source: An assessment of solar coronal jets as switchback precursors
Nina Bizien, Clara Froment, Maria S. Madjarska +2
The origin of large-amplitude magnetic field deflections in the solar wind, known as magnetic switchbacks, is still under debate. These structures, which are ubiquitous in the obse…
