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…
The near-Sun Heliospheric Current Sheet, fluid and kinetic properties
Naïs Fargette, Jonathan P. Eastwood, Tai D. Phan +2
The heliospheric current sheet (HCS) is an important large-scale structure of the heliosphere, and, for the first time, the Parker Solar Probe (PSP) mission enables us to study its…
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…
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…
Using Solar Orbiter as an upstream solar wind monitor for real time space weather predictions
R. Laker, T. S. Horbury, H. O'Brien +11
Coronal mass ejections (CMEs) can create significant disruption to human activities and systems on Earth, much of which can be mitigated with prior warning of the upstream solar wi…
HelioCast: heliospheric forecasting based on white-light observations of the solar corona. I. Solar minimum conditions
Victor Réville, Nicolas Poirier, Athanasios Kouloumvakos +8
We present a new 3D MHD heliospheric model for space-weather forecasting driven by boundary conditions defined from white-light observations of the solar corona. The model is based…
The preferential orientation of magnetic switchbacks, implications for solar magnetic flux transport
Naïs Fargette, Benoit Lavraud, Alexis P. Rouillard +3
We investigate the orientation of the magnetic field deflections in switchbacks (SB) to determine if they are characterised by a possible preferential orientation. We compute the d…
Flux ropes and dynamics of the heliospheric current sheet
V. Réville, N. Fargette, A. P. Rouillard +19
Context. Solar Orbiter and PSP jointly observed the solar wind for the first time in June 2020, capturing data from very different solar wind streams, calm and Alfvénic wind as wel…
Magnetic reconnection as a mechanism to produce multiple protonpopulations and beams locally in the solar wind
B. Lavraud, R. Kieokaew, N. Fargette +37
Context. Spacecraft observations early revealed frequent multiple proton populations in the solar wind. Decades of research on their origin have focused on processes such as magnet…
Characteristic scales of magnetic switchback patches near the Sun and their possible association with solar supergranulation and granulation
Naïs Fargette, Benoit Lavraud, Alexis Rouillard +16
Parker Solar Probe (PSP) data recorded within a heliocentric radial distance of 0.3 AU have revealed a magnetic field dominated by Alfvénic structures that undergo large local vari…
Solar wind rotation rate and shear at coronal hole boundaries, possible consequences for magnetic field inversions
R. F. Pinto, N. Poirier, A. P. Rouillard +6
In-situ measurements by several spacecraft have revealed that the solar wind is frequently perturbed by transient structures (magnetic folds, jets, waves, flux-ropes) that propagat…
Solar Orbiter Observations of the Kelvin-Helmholtz Instability in the Solar Wind
R. Kieokaew, B. Lavraud, Y. Yang +17
The Kelvin-Helmholtz instability (KHI) is a nonlinear shear-driven instability that develops at the interface between shear flows in plasmas. KHI has been inferred in various astro…
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…
