Scale size of cometary bow shocks
, 2023 International audienceWith the upcoming Comet Interceptor mission aiming for a flyby of an hitherto unknown long-period comet, we investigate the expected scale size of the plasma environment to be encountered during this mission.

Rankine–Hugoniot Relations and Magnetic Field Enhancement in Turbulent Shocks
The Astrophysical Journal, 2023 In fast collisionless shocks, the density and magnetic field increase and the plasma is heated. The compression and heating are ultimately determined by the Rankine–Hugoniot relations connecting the upstream and downstream parameters.

Unusual Martian Foreshock Waves Triggered by a Solar Wind Stream Interaction Region
The Astrophysical Journal Letters, 2023 Planetary bow shocks noncollisionally dissipate the incident bulk flow energy of solar wind into some other forms. To what extent and how solar wind disturbances affect the energy dissipation processes at the bow shocks on different planets remain ...

Relativistic electrons generated at Earth's quasi-parallel bow shock. [PDF]
Sci Adv, 2019 Plasma shocks are the primary means of accelerating electrons in planetary and astrophysical settings throughout the universe. Which category of shocks, quasi-perpendicular or quasi-parallel, accelerates electrons more efficiently is debated.

Planetary Evaporation and the Dynamics of Planet Wind/Stellar Wind Bow Shocks [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractWe present initial results of a new campaign of simulations focusing on the interaction of planetary winds with stellar environments using Adaptive Mesh Refinement methods. We have confirmed the results of Stone & Proga (2009) that an azimuthal flow structure is created in the planetary wind due to day/night temperatures differences.

Impact of solar wind turbulence on a planetary bow shock
Astronomy & AstrophysicsOver the past decades, near-Earth spacecraft observations have provided insights into the physics of the bow shock, suggesting that solar wind intrinsic turbulence influences the bow shock dynamics. On the other hand, theoretical studies, based on global numerical simulations, have not yet investigated the global 3D interaction between a turbulent ...

Rankine-Hugoniot relations in turbulent shocks
Frontiers in Physics, 2023 A collisionless shock is often regarded as a discontinuity with a plasma flow across it. Plasma parameters before the shock (upstream) and behind the shock (downstream) are related by the Rankine-Hugoniot relations (RH) which essentially are the mass ...

Magnetohydrodynamic Shocks Revisited: Magnetically Constraining the Upstream Solar Wind Condition
The Astrophysical Journal, 2023 Magnetohydrodynamic (MHD) shocks are commonly found in various space and astrophysical systems. One often encounters the problem that only the magnetic field data are available when studying interplanetary shocks and planetary bow shocks in the solar ...

MESSENGER Observations of Standing Whistler Waves Upstream of Mercury’s Bow Shock
, 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).
