Current sheets in the solar corona : formation, fragmentation and heating [PDF]

, 2011
In this thesis we investigate current sheets in the solar corona. The well known 1D model for the tearing mode instability is presented, before progressing to 2D where we introduce a non-uniform resistivity.

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.

Estimates of magnetotail reconnection rate based on IMAGE FUV and EISCAT measurements [PDF]

Annales Geophysicae, 2005
Dayside merging between the interplanetary and terrestrial magnetic fields couples the solar wind electric field to the Earth's magnetosphere, increases the magnetospheric convection and results in efficient transport of solar wind energy into the ...

Additional acceleration of solar-wind particles in current sheets of the heliosphere [PDF]

, 2015
Particles of fast solar wind in the vicinity of the heliospheric current sheet (HCS) or in a front of interplanetary coronal mass ejections (ICMEs) often reveal very peculiar energy or velocity profiles, density distributions with double or triple peaks,

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]

, 2012
We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Fast plasmoid-mediated reconnection in a solar flare

Nature Communications, 2022
Solar flares provide wide range of observational details about fundamental processes involved. Here, the authors show evidence for magnetic reconnection in a strong confined solar flare displaying all four reconnection flows with plasmoids in the current

Spatial Distribution of Return Flows Occurrence in the Venusian Magnetotail and Its Dependence on Upstream Conditions

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Venus‐ward return flow can significantly influence ion escape from Venus and may therefore play an important role in atmospheric evolution. However, the mechanism driving return flow remains under debate. Here, we investigate the occurrence rate and spatial distribution of ion return flows in the Venusian induced magnetotail, and their ...

Achieving fast reconnection in resistive MHD models via turbulent means [PDF]

Nonlinear Processes in Geophysics, 2012
Astrophysical fluids are generally turbulent and this preexisting turbulence must be taken into account for models of magnetic reconnection in astrophysical, solar or heliospheric environments.

Is Magnetic Reconnection Dominantly Spatially or Temporally Variable: First Results From TRACERS

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The Tandem Reconnection And Cusp Electrodynamics Reconnaissance Satellites (TRACERS) small explorer mission was designed to: Determine whether magnetopause reconnection is primarily spatially or temporally variable for a range of solar wind conditions. Observations from the Analyzers for Cusp Ions (ACIs) on the two TRACERS spacecrafts are used

The influence of Hall currents, plasma viscosity and electron inertia on magnetic reconnection solutions [PDF]

, 2007
This thesis examines magnetic reconnection in the solar corona. Magnetic reconnection is the only mechanism which allows the magnetic topology of magnetized plasmas to be changed. Many of the dynamic processes in the Sun's atmosphere are believed to be
