THEMIS satellite observations of hot flow anomalies at Earth's bow shock [PDF]
Annales Geophysicae, 2017 Hot flow anomalies (HFAs) at Earth's bow shock were identified in Time History of Events and Macroscale Interactions During Substorms (THEMIS) satellite data from 2007 to 2009.

Mercury’s Bow Shock and Magnetopause Variations According to MESSENGER Data
UniverseUsing data from the MESSENGER spacecraft magnetometer that describes the magnetopause and the bow shock crossing points of the Mercury’s magnetosphere, we have calculated the parameters of the paraboloids of revolution approximating the obtained points ...

Solar-Terrestrial Physics, 2020 Study of physical processes in plasma near planets often requires knowledge of the position and shape of the planetary bow shock. Empirical models are usually used since theoretical MHD and kinetic models consume too much computer time and cannot be used

Connection Between Foreshock Structures and the Generation of Magnetosheath Jets: Vlasiator Results
Geophysical Research Letters, 2021 Earth’s magnetosheath consists of shocked solar wind plasma that has been compressed and slowed down at the Earth’s bow shock. Magnetosheath jets are pulses of enhanced dynamic pressure in the magnetosheath. Jets have been observed by numerous spacecraft

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 ...

Simulation of a perpendicular bow shock
Geophysical Research Letters, 1981 Simulations of a high Mach number shock with parameters typical of the earth's bow shock have been performed using a hybrid (particle ions, fluid electrons) code. The simulations reproduce the observed ion reflection and overshoots in the magnetic field and density. These features are shown to be closely associated with ion gyration.
