ANALYTICAL MODEL OF THE PLANETARY BOW SHOCK FOR VARIOUS MAGNETIC FIELD DIRECTIONS BASED ON MHD CALCULATIONS

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

Mercury’s Bow Shock and Magnetopause Variations According to MESSENGER Data

Universe
Using 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 ...

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.

The Milky Way Project MOBStIRS: Parameterizing Infrared Stellar-wind Bow Shock Morphologies with Citizen Science

The Astronomical Journal
Mass-loss influences stellar evolution, especially for massive stars with strong winds. Stellar wind bow shock nebulae driven by Galactic OB stars can be used to measure mass-loss rates ( $\dot{M}$ ).

Probing the Low-velocity Regime of Nonradiative Shocks with Neutron Star Bow Shocks

The Astrophysical Journal Letters
Nonradiative shocks accelerate particles and heat astrophysical plasmas. While supernova remnants are the most well-studied example, neutron star (NS) bow shocks are also nonradiative and Balmer dominated.

Fundamental Parameters for Central Stars of 103 Infrared Bow Shock Nebulae

The Astrophysical Journal
Stellar bow shock nebulae are arcuate shock fronts formed by the interaction of radiation-driven stellar winds and the relative motion of the ambient interstellar material.

Earth’s magnetosphere and outer radiation belt under sub-Alfvénic solar wind

Nature Communications, 2016
The interaction between the Earth’s magnetic field and the solar wind results in the formation of a collisionless bow shock. Here, the authors study an even in which the solar wind Mach number remained steadily below one, leading to the evanescence of ...

Using a Magnetohydrodynamic (MHD) Model to Simulate the Magnetospheric Response to a Kinetic Foreshock Transient

Geophysical Research Letters
A global magnetohydrodynamic model predicts the response of the magnetosphere to the passage of a foreshock transient. We simulate the transient as an antisunward‐ and dawnward‐moving slab of hot tenuous solar wind plasma and weak magnetic field ...
