A 3D Nonequilibrium Ionization Model of a Shock Wave in the Low Corona. I. Extreme-ultraviolet Emission and Inefficient Electron Heating

open access: yesThe Astrophysical Journal
Shocks in the low corona are best observed in the extreme ultraviolet (EUV); however, time-dependent ionization in the postshock region is generally incompatible with the otherwise straightforward plasma diagnostics typically applied to EUV imaging data.

Heating of Heavy Ions by Interplanetary Coronal Mass Ejection Driven Collisionless Shocks [PDF]

open access: yes, 2006
Shock heating and particle acceleration processes are some of the most fundamental physical phenomena of plasma physics, with countless applications in laboratory physics, space physics, and astrophysics.

MP‐DualNet: A Dual‐Branch Deep Learning Approach for Magnetopause Boundary Detection Using Simulated SXI Images

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract The Earth's magnetopause is a key boundary governing solar wind–magnetosphere coupling. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission will provide global soft X‐ray imaging of the magnetosphere through solar wind charge exchange (SWCX) emission, offering a new opportunity for remote sensing of magnetopause dynamics ...

Relating near-Earth observations of an interplanetary coronal mass ejection to the conditions at its site of origin in the solar corona [PDF]

open access: yes, 2005
A halo coronal mass ejection (CME) was detected on January 20, 2004. We use solar remote sensing data (SOHO, Culgoora) and near-Earth in situ data (Cluster) to identify the CME source event and show that it was a long duration flare in which a magnetic ...

Characteristics of Solar Wind Density Depletions During Solar Cycles 23 and 24 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2017
Solar wind density depletions are phenomena that solar wind density is rapidly decreased and keep the state. They are generally believed to be caused by the interplanetary (IP) shocks.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Large-amplitude Whistler Precursors and >MeV Particles Observed at a Weak Interplanetary Shock by Parker Solar Probe

open access: yesThe Astrophysical Journal
We report observations of an interplanetary (IP) shock observed by Parker Solar Probe (PSP) on 2024 September 29 at ∼07:50:29 UTC. PSP was only ∼17.07 R _s from the Sun, making this one of the closest observed IP shocks to date. The IP shock was a weak (

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

Statistics of counter-streaming solar wind suprathermal electrons at solar minimum : STEREO observations [PDF]

open access: yes, 2010
Previous work has shown that solar wind suprathermal electrons can display a number of features in terms of their anisotropy. Of importance is the occurrence of counter-streaming electron patterns, i.e., with "beams" both parallel and anti-parallel to ...
