A wavelet-based model of magnetic turbulence over a Parker spiral field
Andrea Larosa, Francesco Pucci, Francesco Malara +7
The propagation of Solar Energetic Particles (SEPs) through the heliosphere is strongly influenced by solar-wind magnetic turbulence, which governs particle scattering, field-line…
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…
Observation of a Fully-formed Forward--Reverse Shock Pair Due to the Interaction Between Two Coronal Mass Ejections at 0.5 au
D. Trotta, A. Dimmock, X. Blanco-Cano +17
We report direct observations of a fast magnetosonic forward--reverse shock pair observed by Solar Orbiter on March 8, 2022 at the short heliocentric distance of 0.5 au. The struct…
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 of an interplanetary shock observed at 0.07 and 0.7 Astronomical Units by Parker Solar Probe and Solar Orbiter
D. Trotta, A. Larosa, G. Nicolaou +23
The Parker Solar Probe (PSP) and Solar Orbiter (SolO) missions opened a new observational window in the inner heliosphere, which is finally accessible to direct measurements. On Se…
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…
Whistler waves observed by Solar Orbiter / RPW between 0.5 AU and 1 AU
M. Kretzschmar, T. Chust, V. Krasnoselskikh +29
The goal of our study is to detect and characterize the electromagnetic waves that can modify the electron distribution functions, with a special attention to whistler waves. We an…
Direct evidence for magnetic reconnection at the boundaries of magnetic switchbacks with Parker Solar Probe
C. Froment, V. Krasnoselskikh, T. Dudok de Wit +20
Parker Solar Probe's first encounters with the Sun revealed the presence of ubiquitous localised magnetic deflections in the inner heliosphere; these structures, often called switc…
Switchbacks: statistical properties and deviations from alfvénicity
A. Larosa, V. Krasnoselskikh, T. Dudok de Witınst +16
{Parker Solar Probe's first solar encounter has revealed the presence of sudden magnetic field deflections that are called switchbacks and are associated with proton velocity enhan…
Switchbacks in the near-Sun magnetic field: long memory and impact on the turbulence cascade
Thierry Dudok de Wit, Vladimir V. Krasnoselskikh, Stuart D. Bale +14
One of the most striking observations made by Parker Solar Probe during its first solar encounter is the omnipresence of rapid polarity reversals in a magnetic field that is otherw…
