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 ...

Shock excitation of the knots of Hen 3-1475 [PDF]
, 2006 We present new optical STIS HST spectroscopic observations of the jets of the proto-planetary nebula Hen 3-1475. The excitation conditions of the knots of Hen 3-1475 are derived from the observed optical spectra, confirming that the knots are shock ...

Unveiling shocks in planetary nebulae [PDF]
, 2013 The propagation of a shock wave into a medium is expected to heat the material beyond the shock, producing noticeable effects in intensity line ratios such as [O III]/Halpha.

Whistler mode waves upstream of Saturn [PDF]
, 2016 Whistler-mode waves are generated within and can propagate upstream of collisionless shocks. They are known to play a role in electron thermodynamics/acceleration and, under certain conditions, are markedly observed as wave trains preceding the shock ...

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 ...

Asymptotic Steady State Solution to a Bow Shock with an Infinite Mach Number [PDF]
, 2015 The problem of a cold gas flowing past a stationary object is considered. It is shown that at large distances from the obstacle the shock front forms a parabolic solid of revolution.

Efficient Energy Conversion through Vortex Arrays in the Turbulent Magnetosheath
The Astrophysical Journal, 2023 Turbulence is often enhanced when transmitted through a collisionless plasma shock. We investigate how the enhanced turbulent energy in the Earth's magnetosheath effectively dissipates via vortex arrays.

Magnetic Fields Recorded by Chondrules Formed in Nebular Shocks
, 2018 Recent laboratory efforts (Fu et al., 2014) have constrained the remanent magnetizations of chondrules and the magnetic field strengths at which the chondrules were exposed to as they cooled below their Curie points.

Mass Loss From Planetary Nebulae in Elliptical Galaxies [PDF]
, 2009 Early-type galaxies possess a dilute hot (2-10E6 K) gas that is probably the thermalized ejecta of the mass loss from evolving stars. We investigate the processes by which the mass loss from orbiting stars interacts with the stationary hot gas for the ...

Properties of mass-loading shocks, 2. Magnetohydrodynamics [PDF]
, 1992 The one-dimensional magnetohydrodynamics of shocked flows subjected to significant mass loading are considered. Recent observations at comets Giacobini-Zinner and Halley suggest that simple nonreacting MHD is an inappropriate description for active ...
