Bow shock oscillations of Mars under weakly disturbed solar wind conditions [PDF]
Bow shock, where the solar wind first encounters the Martian environment, reflects the complex interplay between the solar wind and Martian upper atmosphere and crustal fields.

Properties and models of the Martian bow shock
Mars does not have a global magnetic field of the internal origin, thus, the solar wind plasma can interact directly with the upper atmosphere and the ionosphere and be shocked with the mass-loading and magnetic pileup processes.

The spectral scalings of magnetic fluctuations upstream and downstream of the Venusian bow shock
We statistically investigate the spectral scalings of magnetic fluctuations at the upstream and downstream regions near the Venusian bow shock and perform a differentiation by shock geometry.

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

On the bow shock in front of Earth’s magnetosphere flows a current due to the curl of the interplanetary magnetic field across the shock. The closure of this current remains uncertain; it is unknown whether the bow shock current closes with the Chapman ...

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.

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.

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.

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

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.
