Electron Acceleration at Earth's Bow Shock Due to Stochastic Shock Drift Acceleration

Geophysical Research Letters
We use the Magnetospheric Multiscale mission (MMS) to study electron acceleration at Earth's quasi‐perpendicular bow shock to address the long‐standing electron injection problem.

Impact of solar-wind turbulence on a planetary bow shock

Astronomy & Astrophysics
Context. The interaction of the solar-wind plasma with a magnetized planet generates a bow-shaped shock ahead of the wind. Over recent decades, near-Earth spacecraft observations have provided insights into the physics of the bow shock, and the findings ...

3D Smoothed Particle Hydrodynamics Models of Betelgeuse’s Bow Shock

, 2013
Betelgeuse, the bright red supergiant (RSG) in Orion, is a runaway star. Its supersonic motion through the interstellar medium has resulted in the formation of a bow shock, a cometary structure pointing in the direction of motion. We present the first 3D

Entropy Generation across Earth's Collisionless Bow Shock

, 2012
International audienceEarth's bow shock is a collisionless shock wave but entropy has never been directly measured across it. The plasma experiments on Cluster and Double Star measure 3D plasma distributions upstream and downstream of the bow shock ...

Intermediate shocks in three-dimensional magnetohydrodynamic bow-shock flows with multiple interacting shock fronts

, 2007
Previous MHD simulations predict that when switch-on shock conditions obtain in the solar wind, the bow shock produced in front of an ellipsoidal obstacle will produce a unique bow shock configuration that includes a concave intermediate shock region at ...

The Inner and Outer Shock Layers of Bow Shocks in Cataclysmic Variables

The Astrophysical Journal Letters
Bow shocks around cataclysmic variables (CVs) have traditionally been identified with a single bright optical arc. This feature has been interpreted as the bow shock formed by the interaction between a sustained outflow and the interstellar medium (ISM).

Disintegration and reformation of intermediate‐shock segments in three‐dimensional MHD bow shock flows

, 2001
Recently, it has been shown that for strong upstream magnetic field, stationary three-dimensional magnetohydrodynamic (MHD) bow shock flows exhibit a complex double-front shock topology with particular segments of the shock fronts being of the ...

Efficient computation of ultraviolet radiation from bow shock waves

, 2014
Ultraviolet(UV)emissions radiated by nitric oxide(NO)and hydroxyl radical(OH)in the bow shock experiment[1]are computed using the direct simulation Monte Carlo(DSMC)method and the Navier–Stokes equations,respectively.Compared to previous studies[2,3],the

Cassini plasma spectrometer measurements of Jovian bow shock structure

, 2003
International audienceThe Cassini spacecraft on its way to Saturn flew by Jupiter and crossed its bow shock more than forty times on the dusk-side of the planet, whereas the early missions targeting Jupiter explored the dawnside. Here we report the first
