Collisionless shocks can be nonstationary with periodic reformation shown in many simulation results, but direct observations are still tenuous and difficult to conclusively interpret. In this study, using Magnetospheric Multiscale (MMS) observations, we

Summary: Context. Shocks produced by outflows from young stars are often observed as bow-shaped structures in which the \(H_{2}\) line strength and morphology are characteristic of the physical and chemical environments and the velocity of the impact. Aims.

Formation of the bow shock indentation: MHD simulation results
Simulation results from a global magnetohydrodynamic (MHD) model are used to examine whether the bow shock has an indentation and characterize its formation conditions, as well as its physical mechanism.

The Martian bow shock stands as the first defense against the solar wind and shapes the Martian magnetosphere. Previous studies showed the correlation between the Martian bow shock location and solar wind parameters.

Foreshock cavitons and spontaneous hot flow anomalies: a statistical study with a global hybrid-Vlasov simulation [PDF]
The foreshock located upstream of Earth's bow shock hosts a wide variety of phenomena related to the reflection of solar wind particles from the bow shock and the subsequent formation of ultra-low-frequency (ULF) waves.

To see or not to see a bow shock [PDF]
OB-stars have the highest luminosities and strongest stellar winds of all stars, which enables them to interact strongly with their surrounding ISM, thus creating bow shocks. These offer us an ideal opportunity to learn more about the ISM. They were first detected and analysed around runaway OB-stars using the IRAS allsky survey by van Buren et al ...

Comparison of accelerated ion populations observed upstream of the bow shocks at Venus and Mars [PDF]
Foreshock ions are compared between Venus and Mars at energies of 0.6~20 keV using the same ion instrument, the Ion Mass Analyser, on board both Venus Express and Mars Express. Venus Express often observes accelerated protons (2~6 times the solar wind

Ion and electron heating at the Martian bow shock. Common for bow shocks or not? [PDF]
Two typical bow shock crossings recorded by the Phobos-2 spacecraft in 1989 are considered in the present paper in order to demonstrate that the Martian bow shock is the shock of “common sense” in spite of peculiarities due to the pick-up ions of the Martian origin and their Larmour radius comparable to the scale size of the interaction region between ...

In Situ Observation of Electron Acceleration by a Double Layer in the Bow Shock
The importance of the electric potential along the field direction in the acceleration of electrons in the quasi-perpendicular bow shock has been proposed.
