Ion distributions upstream and downstream of the Earth's bow shock: first results from Vlasiator [PDF]

Annales Geophysicae, 2013
A novel hybrid-Vlasov code, Vlasiator, is developed for global simulations of magnetospheric plasma kinetics. The code is applied to model the collisionless bow shock on scales of the Earth's magnetosphere in two spatial dimensions and three ...

Kinetic-scale magnetic turbulence and finite Larmor radius effects at Mercury

, 2011
We use a nonstationary generalization of the higher-order structure function technique to investigate statistical properties of the magnetic field fluctuations recorded by MESSENGER spacecraft during its first flyby (01/14/2008) through the near Mercury ...

Kinetically modified parametric instabilities of circularly-polarized Alfven waves: Ion kinetic effects [PDF]

, 2006
Parametric instabilities of parallel propagating, circularly polarized finite amplitude Alfven waves in a uniform background plasma is studied, within a framework of one-dimensional Vlasov description for ions and massless electron fluid, so that kinetic

Dynamics of the foreshock compressional boundary and its connection to foreshock cavities [PDF]

Journal of Geophysical Research: Space Physics, 2013
AbstractWe use several global hybrid (kinetic ions, fluid electrons) simulation runs for steady and time‐varying interplanetary magnetic field (IMF) conditions to examine the dynamics of the foreshock compressional boundary (FCB) and its connection to foreshock cavities.

Extending the Wave Telescope Technique to Larger Numbers of Spacecraft Obtaining Robust Spatial Power Spectra

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The wave telescope is an analysis technique for multi‐point spacecraft data that estimates power spectra in reciprocal position space (k $k$‐space). It has been used to reveal the spatial properties of waves and fluctuations in space plasmas. Originally designed as an analysis tool for 4 spacecraft constellations, new multi‐scale missions such

Large Scale Earth's Bow Shock with Northern IMF as simulated by PIC code in parallel with MHD model

, 2016
In this paper, we propose a 3D kinetic model (Particle-in-Cell PIC ) for the description of the large scale Earth's bow shock. The proposed version is stable and does not require huge or extensive computer resources.

Energy Partition at a Collisionless Supercritical Quasi‐Parallel Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Shocks in collisionless astrophysical plasmas redistribute some of the incident flow energy into both thermal and non‐thermal energy. Quantifying the partition of that energy amongst various particle species or their sub‐populations, and electromagnetic energy, represents a fundamental goal of shock physics.

Strong foreshock signal preceding the L'Aquila (Italy) earthquake (M_w 6.3) of 6 April 2009 [PDF]

Natural Hazards and Earth System Sciences, 2010
We used the earthquake catalogue of INGV extending from 1 January 2006 to 30 June 2009 to detect significant changes before and after the 6 April 2009 L'Aquila mainshock (Mw=6.3) in the seismicity rate, r (events/day), and in b-value.

Propagation Velocities and Growth Rates of Short Large‐Amplitude Magnetic Structures (SLAMS) in the Foreshock of Earth

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Short Large‐Amplitude Magnetic Structures (SLAMS) are believed to play important roles in the physics governing the formation of quasi‐parallel shocks. These isolated non‐linear structures, frequently observed in the foreshock, have been suggested to be building blocks for the shock and have been shown to drive shock reformation. In this work,

A case study of large-amplitude ULF waves in the Martian foreshock

Earth and Planetary Physics, 2020
Foreshock ultralow frequency (ULF) waves constitute a significant physical phenomenon in the plasma environment of terrestrial planets. The occurrence of these waves, associated with backstreaming particles reflected and accelerated at the bow shock ...
