Chondrule Formation in Bow Shocks around Eccentric Planetary Embryos [PDF]
The Astrophysical Journal, 2012 Recent isotopic studies of Martian meteorites by Dauphas & Pourmond (2011) have established that large (~ 3000 km radius) planetary embryos existed in the solar nebula at the same time that chondrules - millimeter-sized igneous inclusions found in ...

Planetary Evaporation and the Dynamics of Planet Wind/Stellar Wind Bow Shocks [PDF]
Proceedings of the International Astronomical Union, 2015 We present initial results of a new campaign of simulations focusing on the interaction of planetary winds with stellar environments using Adaptive Mesh Refinement methods.

Upstream Transients at Planetary Bow Shocks
, 2009 Kinetic processes occurring upstream of planetary bow shocks can greatly perturb the magnetosphere-striking solar wind. Collisionless shocks are highly non-linear systems with complicated feedback mechanisms.

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.

Compound electron acceleration at planetary foreshocks [PDF]
Nature CommunicationsShock waves, the interface of supersonic and subsonic plasma flows, are the primary region for charged particle acceleration in multiple space plasma systems, including Earth’s bow shock, which is readily accessible for in-situ measurements.

Structure of a Quasi-parallel Shock Front
The Astrophysical Journal, 2023 The aim of this study is to compare observations of the magnetic field structure of observed quasi-parallel collisionless shock fronts with the results obtained analytically.

The Astrophysical Journal, 2023 Shock waves are sites of intense plasma heating and charged particle acceleration. In collisionless solar wind plasmas, such acceleration is attributed to shock drift or Fermi acceleration but also to wave–particle resonant interactions.

The Astrophysical Journal, 2023 Thermalization and heating of plasma flows at shocks result in unstable charged-particle distributions that generate a wide range of electromagnetic waves. These waves, in turn, can further accelerate and scatter energetic particles. Thus, the properties

Scattering of Superthermal Ions at Shocks: Dependence on Energy
The Astrophysical Journal, 2023 Diffusive shock acceleration requires the production of backstreaming superthermal ions (injection) as a first step. Such ions can be generated in the process of scattering of ions in the superthermal tail off the shock front. Knowledge of the scattering

Planetary bow shocks: Gasdynamic analytic approach [PDF]
Journal of Geophysical Research: Space Physics, 2003 A new analytical model of the bow shock surface is suggested for reasonably accurate and fast prediction of this boundary's position near obstacles of different shape. For axially symmetric obstacles the model was verified by comparison with experiments and results of gasdynamic code application for a wide range of upstream polytropic indexes, 1.15 <
