Direct Measurement of Polar Coronal Hole-like Solar Wind in its Acceleration Phase
Samuel T. Badman, Yeimy J. Rivera, Michael L. Stevens +38
The early evolution of fast polar coronal hole (PCH) solar wind remains largely unconstrained by in situ measurements. In March 2025, Parker Solar Probe (Parker) at its closest app…
Spherically Polarized Alfvén Waves and the Gosling Boost
Yuliang Ding, Marco Velli, Zesen Huang +6
Alfvén waves are thought to play critical roles in solar wind acceleration and plasma heating in the solar corona and inner heliosphere. Parker Solar Probe (PSP) has highlighted th…
Applications of Fast Magnetic Reconnection Models to the Atmospheres of the Sun and Protoplanetary Disks
Fulvia Pucci, Alkendra Singh, Uma Gorti +4
Partially-ionized plasmas consist of charged and neutral particles whose mutual collisions modify magnetic reconnection compared with the fully-ionized case. The collisions alter t…
Shear-Driven Transition to Isotropically Turbulent Solar Wind Outside the Alfven Critical Zone
D. Ruffolo, W. H. Matthaeus, R. Chhiber +11
Motivated by prior remote observations of a transition from striated solar coronal structures to more isotropic ``flocculated'' fluctuations, we propose that the dynamics of the in…
Magnetic field line twisting by photospheric vortices: energy storage and release
A. F. Rappazzo, M. Velli, R. B. Dahlburg +1
We investigate the dynamics of a closed corona cartesian reduced magnetohydrodynamic (MHD) model where photospheric vortices twist the coronal magnetic field lines. We consider two…
Observational Signatures of Coronal Loop Heating and Cooling Driven by Footpoint Shuffling
R. B. Dahlburg, G. Einaudi, B. D. Taylor +4
The evolution of a coronal loop is studied by means of numerical simulations of the fully compressible three-dimensional magnetohydrodynamic equations using the HYPERION code. The…
"Ideal" tearing and the transition to fast reconnection in the weakly collisional MHD and EMHD regimes
Daniele Del Sarto, Fulvia Pucci, Anna Tenerani +1
This paper discusses the transition to fast growth of the tearing instability in thin current sheets in the collisionless limit where electron inertia drives the reconnection proce…
Proton temperature anisotropy and magnetic reconnection in the solar wind: effects of kinetic instabilities on current sheet stability
Lorenzo Matteini, Simone Landi, Marco Velli +1
We investigate the role of kinetic instabilities driven by a proton anisotropy on the onset of magnetic reconnection by means of 2-D hybrid simulations. The collisionless tearing o…
