Pinching of ICME Flux Rope: Unprecedented Multipoint Observations of Internal Magnetic Reconnection during Gannon’s Superstorm

The Astrophysical Journal Letters
The extreme solar storm of 2024 May 10, during the 25th solar cycle, which recorded a symmetric H component index (Sym-H) reaching −500 nT, was the strongest since the 2003 Halloween storm.

Radiative Signatures of Magnetic Reconnection: An Approach to Remote Probing of Reconnection Dynamics

The Astrophysical Journal
Magnetic reconnection drives a wide range of astrophysical phenomena, including geomagnetic storms, solar flares, and activity in blazars. However, direct measurement of key reconnection observables remains challenging due to the remote and extreme ...

Alfvén Waves from Interchange Reconnection at Separators as a Possible Source of Switchbacks

The Astrophysical Journal
Parker Solar Probe has observed Alfvénic fluctuations of amplitude large enough to occasionally reverse the local magnetic field direction—a phenomenon known as a switchback. Some have attributed switchbacks to reconnection in the low corona between open

On the topology of global coronal magnetic fields [PDF]

, 2014
This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Parker Solar Probe Observations of a Flux Rope Embedded in a Near-Sun Heliospheric Current Sheet Magnetic Reconnection Exhaust

The Astrophysical Journal
In situ observations by Parker Solar Probe (PSP) suggest that the heliospheric current sheet (HCS) undergoes near-continuous magnetic reconnection close to the Sun, in stark contrast to scarce observations of this phenomenon in the HCS at 1 au.

Space- and ground-based investigations of solar wind-magnetosphere-ionosphere coupling [PDF]

, 2006
This paper provides a brief review of the understanding of the coupled solar wind–magnetosphere–ionosphere system that can be attained from observations of the size of the ionospheric polar caps from space and the ground.

Magnetosonic Mach number dependence of the efficiency of reconnection between planetary and interplanetary magnetic fields [PDF]

, 2009
We present a statistical investigation into the magnetosonic Mach number dependence of the efficiency of reconnection at the Earth's dayside magnetopause.

Kinetic Simulation of Energy Cascade Associated with Filamentary Currents in Solar Wind Turbulence

The Astrophysical Journal
The role of magnetic reconnection in energy cascade within solar wind turbulence remains a fundamental unsolved problem in astrophysics. We employ a coarse-grained technique to investigate energy cascades at sub-ion scale within filamentary currents (FCs)
