The () mission has observed near-continuous power in parallel ion cyclotron waves (PICWs) in the young, fast solar wind. These waves are…
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…
On the Relation between Source Region and In-situ Variability of Low Solar Wind Streams
Kai Jaffarove, Tamar Ervin, Stuart D. Bale
Parker Solar Probe (PSP) observed a high speed stream near the Sun () in March 2025. As this stream was observed near the Sun, it allowed for an unparalleled oppo…
