Magnetic reconnection exhausts in the solar wind

, 2016
The restructuring of magnetic fields in plasmas through the process of magnetic reconnection is important in laboratory experiments, magnetospheres and many astrophysical systems. In-situ observations of reconnection processes in the near-Earth environment provide an excellent opportunity to probe the physics of magnetic reconnection. In the solar wind,

Oblique Compressible Waves in the Reconnection Exhaust Region Embedded in the Inner Heliospheric Current Sheet Observed by Parker Solar Probe

The Astrophysical Journal
Magnetic reconnection is an important physical process of energy conversion in the heliosphere. Parker Solar Probe (PSP) passes through current sheets of the inner heliosphere and is likely to encounter magnetic reconnection events there. PSP traversed a

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 ...

Formation of Fan-spine Magnetic Topology through Flux Emergence and Subsequent Jet Production

The Astrophysical Journal Letters
Fan-spine magnetic structure, as a fundamental three-dimensional topology in magnetic reconnection theory, plays a crucial role in producing solar jets. However, how fan-spine configurations form in the solar atmosphere remains elusive. Using the Chinese

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.

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

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.

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)

Key issues on magnetic reconnection at Mercury

Earth and Planetary Physics
Magnetic reconnection processes and their impact on planetary magnetospheric dynamics exhibit significant differences due to differences in upstream solar wind conditions and internal planetary environments.

The observation of possible reconnection events in the boundary changes of solar coronal holes [PDF]

Coronal holes are large scale regions of magnetically open fields which are easily observed in solar soft X-ray images. The boundaries of coronal holes are separatrices between large scale regions of open and closed magnetic fields where one might expect
