Upstream Transients at Planetary Bow Shocks [PDF]

, 2009
Kinetic processes occurring upstream of planetary bow shocks can greatly perturb the magnetosphere-striking solar wind. Collisionless shocks are highly non-linear systems with complicated feedback mechanisms. Transient events form part of the growing evidence that shocks are highly variable and far more complex than a large-scale quasi-static picture ...

Correlated Response of the Martian Dayside Magnetic Pileup Boundary and Bow Shock to Solar Wind and Planetary Drivers

The Astrophysical Journal
The interaction between the supermagnetosonic solar wind and the atmosphere of the weakly magnetized planet Mars forms an induced magnetosphere preceded by a magnetic pileup boundary (MPB) and bow shock (BS).

Properties of mass-loading shocks, 2. Magnetohydrodynamics [PDF]

, 1992
The one-dimensional magnetohydrodynamics of shocked flows subjected to significant mass loading are considered. Recent observations at comets Giacobini-Zinner and Halley suggest that simple nonreacting MHD is an inappropriate description for active ...

Properties of mass-loading shocks: 1. Hydrodynamic considerations [PDF]

, 1991
The one-dimensional hydrodynamics of flows subjected to mass loading are considered anew, with particular emphasis placed on determining the properties of mass-loading shocks. This work has been motivated by recent observations of the outbound Halley bow

Planetary bow shocks: Asymptotic MHD Mach cones [PDF]

Earth, Planets and Space, 2014
A direct approach for determining the asymptotic MHD Mach cone is formulated and solved. An implicit analytical solution enables the calculation of the asymptotic downstream slope of MHD Mach cones at any clock angle for arbitrary Ms, Ma, and ϑbv. The solution obtained includes all previously known symmetric cases.

Cassini encounters with hot flow anomaly-like phenomena at Saturn's bow shock [PDF]

, 2008
The first observations of the kronian equivalent of hot flow anomalies (HFAs) are presented. Using magnetic field and plasma data we discuss two events that were observed upstream of Saturn's bow shock during the first two orbits of the Cassini ...

Radio detections of IR-selected runaway stellar bow shocks [PDF]

, 2022
Massive stars moving at supersonic peculiar velocities through the interstellar medium (ISM) can create bow shocks, arc-like structures at the interface between the stellar wind and the ISM.

Modeling nonthermal emission from stellar bow shocks [PDF]

, 2016
Context. Runaway O- and early B-type stars passing through the interstellar medium at supersonic velocities and characterized by strong stellar winds may produce bow shocks that can serve as particle acceleration sites.

Rankine–Hugoniot Relations and Magnetic Field Enhancement in Turbulent Shocks

The Astrophysical Journal, 2023
In fast collisionless shocks, the density and magnetic field increase and the plasma is heated. The compression and heating are ultimately determined by the Rankine–Hugoniot relations connecting the upstream and downstream parameters.

X-ray study of bow shocks in runaway stars [PDF]

, 2017
peer reviewedMassive runaway stars produce bow shocks through the interaction of their winds with the interstellar medium, with the prospect for particle acceleration by the shocks. These objects are consequently candidates for non-thermal emission.
