The Observations of Magnetic Reconnection during the Interaction Process of Two Active Region Filaments

The Astrophysical Journal
We investigate the interaction between two filaments (F1 and F2) and their subsequent magnetic reconnection in active region (AR) NOAA 13296 and AR NOAA 13293 on 2023 May 9, utilizing high spatial and temporal resolution and multiwavelength observational

JET Formation in Solar Atmosphere Due to Magnetic Reconnection

The Astrophysical Journal, 2017
Using numerical simulations, we show that jets with features of type II spicules and cold coronal jets corresponding to temperatures $10^{4}$ K can be formed due to magnetic reconnection in a scenario in presence of magnetic resistivity. For this we model the low chromosphere-corona region using the C7 equilibrium solar atmosphere model and assuming ...

Connecting Solar Wind Velocity Spikes Measured by Solar Orbiter and Coronal Brightenings Observed by SDO

The Astrophysical Journal Letters
The Parker Solar Probe's discovery that magnetic switchbacks and velocity spikes in the young solar wind are abundant has prompted intensive research into their origin(s) and formation mechanism(s) in the solar atmosphere.

The Role of Reconnection at Magnetic Separators in Complex Solar Flare Ribbons

The Astrophysical Journal
Solar flare ribbons, manifesting as transient brightenings in the chromosphere, are believed to trace the footpoints of magnetic field lines reconnecting higher in the solar atmosphere.

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

From Photospheric Footpoint Motion to Plasmoid Ejection: A Two-stage Reconnection Process in a Small-scale Chromospheric Jet

The Astrophysical Journal Letters
Using high-spatiotemporal-resolution multiwavelength observations from the New Vacuum Solar Telescope and the Solar Dynamics Observatory, we present a detailed analysis of a small-scale chromospheric jet driven by plasmoid-mediated magnetic reconnection.

Solar flux emergence : a three-dimensional numerical study [PDF]

, 2008
Flux is continually emerging on the Sun, making its way from the solar interior up into the atmosphere. Emergence occurs on small-scales in the quiet Sun where magnetic fragments emerge, interact and cancel and on large-scales in active regions where ...

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
