Comparison of accelerated ion populations observed upstream of the bow shocks at Venus and Mars [PDF]
Annales Geophysicae, 2011 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]
Annales Geophysicae, 2021 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.

THE EXISTENCE AND NATURE OF THE INTERSTELLAR BOW SHOCK [PDF]
The Astrophysical Journal, 2013 We report a new diagnostic between two different states of the local interstellar medium (LISM) near our solar system using a sensitivity study constrained by several distinct and complementary observations of the LISM, solar wind, and inner heliosphere.

In Situ Observation of Electron Acceleration by a Double Layer in the Bow Shock
The Astrophysical Journal, 2023 The importance of the electric potential along the field direction in the acceleration of electrons in the quasi-perpendicular bow shock has been proposed.

Ion and electron heating at the Martian bow shock. Common for bow shocks or not? [PDF]
Earth, Planets and Space, 2014 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 ...

The role of the bow shock in solar wind-magnetosphere coupling [PDF]
Annales Geophysicae, 2011 In this paper we examine the role of the bow shock in coupling solar wind energy to the magnetosphere using global magnetohydrodynamic simulations of the solar wind-magnetosphere interaction with southward IMF.

Double Layers in the Earth's Bow Shock
Geophysical Research Letters, 2022 AbstractWe present Magnetospheric Multiscale observations of electrostatic double layers in quasi‐perpendicular Earth's bow shock. These double layers have predominantly parallel electric field with amplitudes up to 100 mV/m, spatial widths of 50–700 m, and plasma frame speeds within 100 km/s. The potential drop across a single double layer is 2%–7% of

Martian Bow Shock and Magnetic Pile-Up Barrier Formation Due to the Exosphere Ion Mass-Loading [PDF]
Journal of Astronomy and Space Sciences, 2011 Bow shock, formed by the interaction between the solar wind and a planet, is generated in different patterns depending on the conditions of the planet.

Magnetic field fluctuations across the Earth’s bow shock [PDF]
Annales Geophysicae, 2001 We present a statistical analysis of 132 dayside (LT 0700-1700) bow shock crossings of the AMPTE/IRM spacecraft. We perform a superposed epoch analysis of low frequency, magnetic power spectra some minutes up-stream and downstream of the bow shock ...

Bow shocks, bow waves, and dust waves – III. Diagnostics [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT Stellar bow shocks, bow waves, and dust waves all result from the action of a star’s wind and radiation pressure on a stream of dusty plasma that flows past it. The dust in these bows emits prominently at mid-infrared wavelengths in the range 8 to 60 $\mu$m.
