2022年2月2日 · Here we present multi-wavelength imaging and spectral evidence for magnetic reconnection in a strong confined solar flare, traced by the cool plasma of the interacting filament and...

2022年10月8日 · Here, we report a well-designed experimental investigation on magnetic reconnections in a hybrid collisional-collisionless regime by interactions between laser-ablated copper and plastic plasmas....

2021年5月4日 · In this paper, we demonstrate the important role of plasmoids in shaping the particle energy spectrum in relativistic reconnection (i.e., with upstream magnetization σup ≫ 1). Using 2D particle-in-cell simulations in pair plasmas with σup = 10 and 100, we study a secondary particle energization process that takes place inside compressing plasmoids.

2024年3月28日 · Utilizing joint observations from the Goode Solar Telescope and the Solar Dynamics Observatory, we discovered a small-scale eruptive phenomenon in NOAA Active Region 13085, characterized by clear reconnection cusp structures, supported by nonlinear force-free field extrapolation results.

2024年8月30日 · Plasmoid instability accelerates reconnection in collisional plasmas by transforming a laminar reconnection layer into numerous plasmoids connected by secondary current sheets in two dimensions (2D) and by fostering self-generated turbulent reconnection in three dimensions (3D).

The animation shows how reconnection splits the induced magnetotail of Venus, causing most of the plasma in the tail to be ejected into space. It also forms a plasmoid structure - the closed loop - which heads towards the planet and channels a fraction of the energy flux of the solar wind into the night-side atmosphere.

2024年5月3日 · The animation comprehensively illustrates the magnetic reconnection process of a minor solar flare, incorporating Hα images from GST/VIS and 171 Å images from SDO/AIA, covering the period from 19:31:04 UT to 19:58:22 UT, with a duration of about 27 minutes. This static image only displays three key frames from the animation.

Magnetic reconnection in the deep solar atmosphere can give rise to enhanced emission in the Balmer hydrogen lines, a phenomenon referred to as Ellerman bombs. Aims. To effectively trace magnetic reconnection below the canopy of chromospheric fibrils, we analyzed unique spectroscopic observations of Ellerman bombs in the H α line.

Magnetic reconnection is a multi-faceted process of energy conversion in astrophysical, space and laboratory plasmas that operates at microscopic scales but has macroscopic drivers and...

experimental evidence for plasmoid formation and dynamics in laser-driven high-b reconnection experiments. Magnetic reconnection is the process by which magnetic fields in plasmas change their topologies and release magnetic
