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…
Alfvénic versus non-Alfvénic turbulence in the inner heliosphere as observed by Parker Solar Probe
Chen Shi, Marco Velli, Olga Panasenco +20
We make use of the Parker Solar Probe (PSP) data to explore the nature of solar wind turbulence focusing on the Alfvénic character and power spectra of the fluctuations and their d…
Investigating the origin of the FIP effect with a shell turbulence model
Victor Réville, Alexis P. Rouillard, Marco Velli +4
The enrichment of coronal loops and the slow solar wind with elements that have low First Ionisation Potential, known as the FIP effect, has often been interpreted as the tracer of…
Impact of solar magnetic field amplitude and geometry on cosmic rays diffusion coefficients in the inner heliosphere
Barbara Perri, Allan Sacha Brun, Antoine Strugarek +1
Cosmic rays (CRs) are tracers of solar events when they are associated with solar flares, but also galactic events when they come from outside our solar system. SEPs are correlated…
The Solar Wind Angular Momentum Flux as Observed by Parker Solar Probe
Adam J. Finley, Sean P. Matt, Victor Réville +9
The long-term evolution of the Sun's rotation period cannot be directly observed, and is instead inferred from trends in the measured rotation periods of other Sun-like stars. Assu…
Alfvén-wave driven magnetic rotator winds from low-mass stars I: rotation dependences of magnetic braking and mass-loss rate
Munehito Shoda, Takeru K. Suzuki, Sean P. Matt +7
Observations of stellar rotation show that low-mass stars lose angular momentum during the main sequence. We simulate the winds of Sun-like stars with a range of rotation rates, co…
Tearing instability and periodic density perturbations in the slow solar wind
Victor Réville, Marco Velli, Alexis Rouillard +4
In contrast with the fast solar wind, that originates in coronal holes, the source of the slow solar wind is still debated. Often intermittent and enriched with low FIP elements --…
Detailed imaging of coronal rays with the Parker Solar Probe
Nicolas Poirier, Athanasios Kouloumvakos, Alexis P. Rouillard +13
The Wide-field Imager for Solar PRobe (WISPR) obtained the first high-resolution images of coronal rays at heights below 15 R when the Parker Solar Probe (PSP) was located…
Direct Detection of Solar Angular Momentum Loss with the Wind Spacecraft
Adam J. Finley, Amy L. Hewitt, Sean P. Matt +3
The rate at which the solar wind extracts angular momentum from the Sun has been predicted by theoretical models for many decades, and yet we lack a conclusive measurement from in-…
Propagation of Alfvén waves in the expanding solar wind with the fast-slow stream interaction
Chen Shi, Marco Velli, Anna Tenerani +2
We carry out two-dimensional magnetohydrodynamic (MHD) simulations of an ensemble of Alfvénic fluctuations propagating in a structured, expanding solar wind including the presence…
Reconstructing Extreme Space Weather from Planet Hosting Stars
V. S. Airapetian, V. Adibekyan, M. Ansdell +80
The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide…
Effect of the exoplanet magnetic field topology on its magnetospheric radio emission
J. Varela, V. Réville, A. S. Brun +2
The magnetized wind from stars that impact exoplanets should lead to radio emissions. According to the scaling laws derived in the solar system, the radio emission should depend on…
Global solar magnetic field organization in the outer corona: influence on the solar wind speed and mass flux over the cycle
Victor Réville, Allan Sacha Brun
The dynamics of the solar wind depends intrinsically on the structure of the global solar magnetic field, which undergoes fundamental changes over the 11-yr solar cycle. For instan…
Age dependence of wind properties for solar type stars: a 3d study
Victor Réville, Colin P. Folsom, Antoine Strugarek +1
Young and rapidly rotating stars are known for intense, dynamo generated magnetic fields. Spectropolarimetric observations of those stars in precisely aged clusters are key input f…
Magnetic games between a planet and its host star: the key role of topology
A. Strugarek, A. S. Brun, S. P. Matt +1
Magnetic interactions between a star and a close-in planet are postulated to be a source of enhanced emissions and to play a role in the secular evolution of the orbital system. Cl…
