Evolution and Impact of Switchbacks Throughout the Heliosphere

Alfred Mallet, Chen Shi, Anna Tenerani +23

Magnetic switchbacks are large-amplitude fluctuations in the interplanetary magnetic field, and appear frequently in the near-Sun solar wind explored recently by Parker Solar Probe…

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…

Velocity-space turbulent cascade in the near-Sun solar wind: first insights from the Parker Solar Probe mission

A. Larosa, O. Pezzi, T. Bowen +11

In space plasmas, the rarity of collisions leads to complex structures in the velocity space where a turbulent cascade of the velocity distribution function fluctuations is thought…

Evolution of the Shock Properties of the 2023 March 13 Event from In-Situ and Remote-Sensing Data

Federica Chiappetta, Giuseppe Nisticò, Massimo Chimenti +6

Shocks driven by coronal mass ejections (CMEs) are the most powerful accelerators of gradual solar energetic particles (SEPs) in the inner heliosphere. On 2023 March 13, a halo CME…

A Tale of Two Shocks

Robert F. Wimmer-Schweingruber, Domenico Trotta, Rungployphan Kieokaew +23

Energetic particles in interplanetary space are normally measured at time scales that are long compared to the ion gyroperiod. Such observations by necessity average out the microp…

The relation between magnetic switchbacks and turbulence in the inner heliosphere

A. Larosa, C. H. K Chen, J. R. McIntyre +1

We investigate the relation between turbulence and magnetic field switchbacks in the inner heliosphere below 0.5 AU in a distance and scale dependent manner. The analysis is perfor…

Properties underlying the variation of the magnetic field spectral index in the inner solar wind

J. R. McIntyre, C. H. K. Chen, A. Larosa

Using data from orbits one to eleven of the Parker Solar Probe (PSP) mission, the magnetic field spectral index was measured across a range of heliocentric distances. The previousl…

Whistler waves generated inside magnetic dips in the young solar wind: observations of the Search-Coil Magnetometer on board Parker Solar Probe

C. Froment, O. V. Agapitov, V. Krasnoselskikh +11

Context. Whistler waves are electromagnetic waves produced by electron-driven instabilities, that in turn can reshape the electron distributions via wave-particle interactions. In…
