SUPRATHERMAL ELECTRONS AT SATURN'S BOW SHOCK [PDF]
The Astrophysical Journal, 2016 ABSTRACT The leading explanation for the origin of galactic cosmic rays is particle acceleration at the shocks surrounding young supernova remnants (SNRs), although crucial aspects of the acceleration process are unclear. The similar collisionless plasma shocks frequently encountered by spacecraft in the solar wind are generally far ...

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.

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.

Nonthermal Emission from Stellar Bow Shocks [PDF]
The Astrophysical Journal, 2018 Abstract Since the detection of nonthermal radio emission from the bow shock of the massive runaway star BD +43°3654, simple models have predicted high-energy emission, at X-rays and gamma-rays, from these Galactic sources. Observational searches for this emission so far give no conclusive evidence but a few candidates at gamma-rays.

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.

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 ...

Pulsar bow-shock nebulae [PDF]
Astronomy & Astrophysics, 2001 Pulsar bow-shock nebulae originate from the interaction of the ambient medium with the wind of a moving pulsar. The properties of these nebulae depend on both the physical conditions in the ambient medium and the characteristics of the pulsar wind, and may thus represent a powerful diagnostic tool.

THE RETURN OF THE BOW SHOCK [PDF]
The Astrophysical Journal, 2014 Recently it has been discussed whether a bow shock ahead of the heliospheric stagnation region does exist or not. This discussion was triggered by measurements indicating that the Alfv n speed and that of fast magnetosonic waves are higher than the flow speed of the local interstellar medium (LISM) relative to the heliosphere and resulted in the ...

MESSENGER Observations of Standing Whistler Waves Upstream of Mercury's Bow Shock
Geophysical Research Letters, 2023 This paper reports on the standing whistler waves upstream of Mercury's quasi‐perpendicular bow shock. Using MESSENGER's magnetometer data, 36 wave events were identified during interplanetary coronal mass ejections (ICMEs).
