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,

MMS Observations of the Energetic Particles Within Kelvin‐Helmholtz Waves at the Boundary of the 10 May 2024 Coronal Mass Ejection (CME)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.

Coordinated cluster and ground-based instrument observation of transient changes in the magnetopause boundary layer during an interval of predominantly northward IMF: Relation to reconnection pulses and FTE signatures [PDF]

, 2001
We study a series of transient entries into the low-latitude boundary layer (LLBL) of all four Cluster spacecraft during an outbound pass through the mid-afternoon magnetopause ([XGSM,YGSM,ZGSM] ≈ [2,7,9]RE).

Basic Pattern of Three-dimensional Magnetic Reconnection within Strongly Turbulent Current Sheets

The Astrophysical Journal
Magnetic reconnection is a fundamental mechanism of driving eruptive phenomena of different scales and may be coupled with turbulence as suggested by recent remote-sensing and in situ observations.

Magnetic skeletons and 3D magnetic reconnection [PDF]

, 2008
Electronic version does not contain additional mpeg filesThe upper atmosphere of the sun, the solar corona, is approximately 1,000,000K hotter than the surface of the Sun, a property which cannot be explained by the normal processes of heat conduction ...

Simultaneous in-situ observations of the signature of dayside reconnection at the high and low latitude magnetopause [PDF]

, 2005
We present magnetic field and particle data recorded by the Cluster and Geotail satellites in the vicinity of the high- and low-latitude dayside magnetopause, re- spectively, on 17 February 2003. A favourable conjunction of these spacecraft culminated in
