Shocklets and Short Large Amplitude Magnetic Structures (SLAMS) in the High Mach Foreshock of Venus [PDF]
Geophysical Research Letters, 2023 Shocklets and short large‐amplitude magnetic structures (SLAMS) are steepened magnetic fluctuations commonly found in Earth's upstream foreshock. Here we present Venus Express observations from the 26th of February 2009 establishing their existence in ...

New Physical Implications From Revisiting Foreshock Activity in Southern California
Geophysical Research Letters, 2023 Foreshock analysis promises new insights into the earthquake nucleation process and could potentially improve earthquake forecasting. Well‐performing clustering models like the Epidemic‐Type Aftershock Sequence (ETAS) model assume that foreshocks and ...

On the edge of the foreshock: model-data comparisons [PDF]
Annales Geophysicae, 2008 We present the results of a global hybrid code simulation for the solar wind-interaction with the Earth's magnetosphere during an interval of steady radial IMF.

The statistics of foreshock cavities: results of a Cluster survey [PDF]
Annales Geophysicae, 2008 We use Cluster magnetic field, thermal ion, and energetic particle observations upstream of the Earth's bow shock to investigate the occurrence patterns of foreshock cavities. Such cavities are thought to form when bundles of magnetic field connect to

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.

Statistical study of foreshock cavitons [PDF]
Annales Geophysicae, 2013 In this work we perform a statistical analysis of 92 foreshock cavitons observed with the Cluster spacecraft 1 during the period 2001–2006. We analyze time intervals during which the spacecraft was located in the Earth's foreshock with durations ...

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 ...

Connection Between Foreshock Structures and the Generation of Magnetosheath Jets: Vlasiator Results
Geophysical Research Letters, 2021 Earth’s magnetosheath consists of shocked solar wind plasma that has been compressed and slowed down at the Earth’s bow shock. Magnetosheath jets are pulses of enhanced dynamic pressure in the magnetosheath. Jets have been observed by numerous spacecraft

Impact of Foreshock Transients on the Flank Magnetopause and Magnetosphere and the Ionosphere
Frontiers in Astronomy and Space Sciences, 2021 Mesoscale (on the scales of a few minutes and a few RE) magnetosheath and magnetopause perturbations driven by foreshock transients have been observed in the flank magnetotail.

Foreshock-like density cavity in the outflow region of magnetotail reconnection [PDF]
Annales Geophysicae, 2009 During Cluster spacecraft crossing of the magnetotail, a novel density depleted cavity in association with magnetic compressions in the outflow region of reconnection was observed.
