A study of ionopause perturbation and associated boundary wave formation at Venus [PDF]

, 2017
Magnetometer and electron spectrometer data from Venus Express (VEX) are used to investigate the occurrence of boundary wave phenomenon occurring in the vicinity of the Venusian terminator. On 26 June 2006, VEX data show the ionosphere to be unmagnetized

Investigation of the Interaction Between Magnetosheath Reconnection and Magnetopause Reconnection Driven by Oblique Interplanetary Tangential Discontinuity Using Three-Dimensional Global Hybrid Simulation [PDF]

, 2021
Magnetosheath reconnection due to the interaction of an interplanetary directional discontinuity with the bow shock and Earth's magnetosphere under an initially northward interplanetary magnetic field (IMF) has been investigated in previous simulations ...

Radon earthquake precursor studies in Iceland [PDF]

, 1981
Discrete samples of geothermal water have been collected from a network of nine stations for analysis of radon (^(222)Rn) content. The sampling network consisted of wells that range in wellhead temperature from 48°C to 100°C, and the depths range from 38

Magnetic field amplification and electron acceleration to near-energy equipartition with ions by a mildly relativistic quasi-parallel plasma protoshock

, 2010
The prompt emissions of gamma-ray bursts are seeded by radiating ultrarelativistic electrons. Internal shocks propagating through a jet launched by a stellar implosion, are expected to amplify the magnetic field & accelerate electrons.

Transient upstream mesoscale structures: drivers of solar-quiet space weather

Frontiers in Astronomy and Space Sciences
In recent years, it has become increasingly clear that space weather disturbances can be triggered by transient upstream mesoscale structures (TUMS), independently of the occurrence of large-scale solar wind (SW) structures, such as interplanetary ...

A Single Deformed Bow Shock for Titan-Saturn System [PDF]

, 2017
During periods of high solar wind pressure, Saturn's bow shock is pushed inside Titan's orbit exposing the moon and its ionosphere to the solar wind. The Cassini spacecraft's T96 encounter with Titan occurred during such a period and showed evidence for ...

Relativistic electrons generated at Earth's quasi-parallel bow shock. [PDF]

, 2019
Plasma shocks are the primary means of accelerating electrons in planetary and astrophysical settings throughout the universe. Which category of shocks, quasi-perpendicular or quasi-parallel, accelerates electrons more efficiently is debated.

Relationship Between Foreshock Structures and Magnetosheath Jets

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Plasma structures with enhanced dynamic pressure know as jets are frequently observed in the magnetosheath. We examine a possible connection of these jets with structures reported in the foreshock like SLAMS or plasmoids. A statistical study of the relation of the upstream conditions and the occurrence rates of magnetosheath (MSH) jets and ...

Ion Energization and Acceleration Associated With Foreshock Bubbles: Results From a Hybrid‐Vlasov Simulation and MMS Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Foreshock Bubbles (FBs) are large‐scale transient structures found in Earth's foreshock region and are associated with foreshock‐discontinuity interaction. FBs play a significant role in accelerating and energizing plasma through various mechanisms.
