Intense Whistler-mode Waves at Foreshock Transients: Characteristics and Regimes of Wave−Particle Resonant Interaction [PDF]
Astrophysical Journal, 2022 Thermalization and heating of plasma flows at shocks result in unstable charged-particle distributions that generate a wide range of electromagnetic waves. These waves, in turn, can further accelerate and scatter energetic particles. Thus, the properties

The Geoeffectiveness of Solar Wind Current Sheets and Its Modulation by Foreshock Ions
Geophysical Research Letters, 2022 We examined the evolution of 34 solar wind bifurcated current sheets in the magnetosheath and their magnetospheric responses, using the in‐situ observations of the THEMIS probes and the GOES satellites.

A global view of Pc3 wave activity in near-Earth space: Results from hybrid-Vlasov simulations
Frontiers in Astronomy and Space Sciences, 2022 Ultra-low frequency (ULF) waves in the Pc3 range, with periods between 10–45 s, are routinely observed in Earth’s dayside magnetosphere. They are thought to originate in the foreshock, which extends upstream of the quasi-parallel bow shock and is ...

Cluster-based foreshock discrimination model with flexible time horizon and mainshock magnitudes
Progress in Earth and Planetary Science, 2023 Foreshock detection before mainshock occurrence is an important challenge limiting the short-term forecasts of large earthquakes. Various models for predicting mainshocks based on discrimination of foreshocks activity have been proposed, but many of them

Ultra‐low Frequency Foreshock Waves and Ion Dynamics at Mars
Journal of Geophysical Research - Space Physics, 2022 We study the solar wind interaction with Mars in a global three‐dimensional hybrid model. A well‐developed, vast ion foreshock forms under a strongly flow‐aligned interplanetary magnetic field (IMF) configuration but otherwise nominal solar wind and ...

Magnetopause Reconnection and Indents Induced by Foreshock Turbulence [PDF]
Geophysical Research Letters, 2021 Based on global hybrid simulation results, we predict that foreshock turbulence can reach the magnetopause and lead to reconnection as well as Earth‐sized indents. Both the interplanetary magnetic field (IMF) and solar wind are constant in our simulation,

Strain rate and temperature dependence of Omori law scaling constants of AE data: Implications for earthquake foreshock-aftershock sequences [PDF]
, 2004 Little is known about the temperature and strain rate dependence of acoustic emission AE activity (AE). Hence, we carried out a preliminary series of flow-through triaxial compression tests on porous sandstones at different temperatures and strain rates.
