The Astronomical JournalUsing global magnetohydrodynamics simulations, we have developed a three-dimensional parametric model for the Venusian bow shock based on a generalized conic section function defined by six parameters, with the effects of the solar wind magnetosonic Mach

Statistical survey of day-side magnetospheric current flow using Cluster observations: bow shock [PDF]
Annales Geophysicae, 2018 We present the first comprehensive statistical survey of the day-side terrestrial bow shock current system based on a large number of Cluster spacecraft bow shock crossings.

Bow shock models of Herbig-Haro objects [PDF]
Symposium - International Astronomical Union, 1987 It has recently been found that models of a radiating bow shock can explain qualitatively the strange emission line profiles observed in some Herbig-Haro (H-H) objects. It is also possible to compare directly the emission line intensity maps predicted from these models with CCD images of H-H objects.

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

Spatial distribution of upstream magnetospheric ≥50 keV ions [PDF]
Annales Geophysicae, 2000 We present for the first time a statistical study of \geq50 keV ion events of a magnetospheric origin upstream from Earth's bow shock. The statistical analysis of the 50-220 keV ion events observed by the IMP-8 spacecraft shows: (1) a dawn-dusk ...

Stability Analysis of Bow Shocks
The Astrophysical Journal, 1996 We present a linear stability analysis of bow shocks created by the interaction of a spherical wind moving with respect to its surrounding medium. The bounding shocks are assumed isothermal and with Mach number M = infinity. Following Soker (1990) we study the evolution of short wavelength perturbations.

Numerical Simulation of the Effect of Swing Center on a Supersonic Split Line Nozzle
气体物理A numerical investigation was performed in the present work to uncover the effect of swing center on a supersonic split line nozzle. Detailed nozzle internal flow and thrust performance were analysed, for serval swing center positions.

Spatial scales of the magnetic ramp at the Venusian bow shock [PDF]
Annales Geophysicae, 2011 Typically multi-spacecraft missions are ideally suited to the study of shock spatial scales due to the separation of temporal and spatial variations. These missions are not possible at all locations and therefore in-situ multi-spacecraft measurements ...

Bow Shock and Upstream Phenomena at Mars [PDF]
Space Science Reviews, 2004 Mars Global Surveyor is the sixth spacecraft to return measurements of the Martian bow shock. The earlier missions were Mariner 4 (1964), Mars 2 and 3 (1972), Mars 5 (1975) and Phobos 2 (1989) (see reviews by Gringauz, 1981; Slavin and Holzer, 1982; Russell, 1985; Vaisberg, 1992a,b; Zakharov, 1992).
