Statistical Evaluation of a Foreshock Transient Model Using Ground‐Based ULF Wave Observations
Geophysical Research LettersHot flow anomalies and foreshock bubbles are discontinuity–driven foreshock transients that generate significant geospace disturbances. A recently developed analytical model can predict their upstream perturbations.

Foreshock Ion Properties at Earth's Bow Shock: Dependence on Upstream Conditions and Shock Geometry
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract Solar wind ion reflection at collisionless shocks regulates foreshock plasma dynamics, yet the quantitative dependence of foreshock ion properties on upstream and shock‐related parameters remains unclear, causing difficulties in predicting foreshock disturbances.

Transient Foreshock Structures Upstream of Mars: Implications of the Small Martian Bow Shock [PDF]
Geophysical Research Letters, 2023 The typical subsolar stand‐off distance of Mars' bow shock is of the order of a solar wind ion convective gyroradius, making it highly non‐planar to incident ions.

New Observations of Mercury's Foreshock Made by BepiColombo
International audienceStudies of the region just upstream of Earth's bow shock - known as its foreshock - have revealed the presence of transient particle populations with characteristics unlike either the upstream solar wind or the downstream plasma of ...

Preacceleration in the Electron Foreshock. I. Electron Acoustic Waves [PDF]
Astrophysical Journal, 2022 To undergo diffusive shock acceleration, electrons need to be preaccelerated to increase their energies by several orders of magnitude, else their gyroradii will be smaller than the finite width of the shock.

On the correlations between the largest foreshocks and mainshocks of earthquake sequences in Taiwan
Frontiers in Earth Science, 2023 We collected a data set of mainshocks and their respective largest foreshocks of 38 earthquake sequences in Taiwan. The plot of local magnitude, ML, of a mainshock (denoted by MLm) versus ML of its largest foreshock (denoted by MLf) shows an increase in ...

The electron foreshock at high-Mach-number non-relativistic oblique shocks [PDF]
Physics of Plasmas, 2022 In the Universe, matter outside of stars and compact objects is mostly composed of collisionless plasma. The interaction of a supersonic plasma flow with an obstacle results in collisionless shocks that are often associated with intense nonthermal ...
