Linear Growth Rate of Compressible Tearing Instability in a Force-Free Current Sheet
Chen Shi, Marco Velli
We investigate the linear growth rate of tearing instability in a resistive force-free current sheet using the linearized fully-compressible magnetohydrodynamics (MHD) equations. O…
Bifurcations in the Heliosphere: Global-scale Coronal Pseudostreamer Evolution and the Creation of Secondary Heliospheric Current Sheets
Lizet S. Casillas, Benjamin J. Lynch, Victor Réville +2
The heliospheric current sheet (HCS) is the boundary between open magnetic fields of opposite polarity in the solar wind that connect back to their respective open flux regions in…
Potential Solar Precursors to Magnetic Switchbacks
Durgesh Tripathi, Maria S. Madjarska, Judy Karpen +9
The origin of magnetic switchbacks-large-amplitude, spherically polarized magnetic-field fluctuations with local polarity inversions shown to be nearly ubiquitous in the inner heli…
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…
Three dimensional, spherically polarized magnetic fields
Anna Tenerani, Marco Velli
Turbulence in the solar wind is characterized by Alfvénic fluctuations that exhibit spherical polarization, a geometric condition resulting in the nearly constant magnitude of the…
Magnetic switchback formation: a review of proposed mechanisms
Peter F. Wyper, Jonathan Squire, Etienne Pariat +19
Magnetic switchbacks are large amplitude deflections of the magnetic field within the solar wind. They are Alfvénic in character and so are associated with a spike in velocity and…
Solar Wind Classifications at Mars using Machine Learning Techniques
Catherine E. Regan, Silvia Ferro, Austin M. Smith +5
Understanding solar wind variability throughout the heliosphere is essential for fundamental space physics and future exploration of the Moon and Mars. The Mars Atmosphere and Vola…
Properties of current sheets in two-dimensional tearing-mediated incompressible magnetohydrodynamic turbulence
Chen Shi, Marco Velli, Nikos Sioulas +1
It is well known that the nonlinear evolution of magnetohydrodynamic (MHD) turbulence generates current sheets. In the solar wind turbulence, current sheets are frequently observed…
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…
Coupling the solar surface and the corona: coronal rotation, Alfvén wave-driven polar plumes
R. F. Pinto, R. Grappin, M. Velli +1
The dynamical response of the solar corona to surface and sub-surface perturbations depends on the chromospheric stratification, and specifically on how efficiently these layers re…
Coupling Photosphere and Corona: Linear and Turbulent Regimes
A. Verdini, R. Grappin, M. Velli
In a recent work Grappin et al. [1] have shown that low- frequency movements can be transmitted from one footpoint to the other along a magnetic loop, thus mimicking a friction eff…
