An asymmetric solar wind termination shock
Nature, 2008Voyager 2 crossed the solar wind termination shock at 83.7 au in the southern hemisphere, approximately 10 au closer to the Sun than found by Voyager 1 in the north. This asymmetry could indicate an asymmetric pressure from an interstellar magnetic field, from transient-induced shock motion, or from the solar wind dynamic pressure.

In astrophysical settings, termination shocks where strong stellar wind outflows interact with the surrounding environments tend to take place in dusty regions. Just to name a few, star formation regions, planetary nebulae, supernova remnants and active galactic nuclei are all good examples.

We find that for reasonable choices of our parameters the compression ratio does not depart very much from the hydrodynamical value and stays between 3 and 4. If synchrotron electrons are produced via first order Fermi processes, then observations of spectral indices suggest compression ratios of about 4.

Multifractal Turbulence at the Termination Shock
AIP Conference Proceedings, 2010We consider the multifractal spectra of fluctuations of the interplanetary magnetic field strength before and after shock crossing by Voyager 1 near 85 and 95 AU from the Sun, correspondingly. We show that the multifractal scaling of magnetic fields is asymmetric in the outer heliosphere, in contrast to the symmetric spectrum observed in the ...

The Heliospheric Termination Shock
Space Science Reviews, 2012The heliospheric termination shock is a vast, spheroidal shock wave marking the transition from the supersonic solar wind to the slower flow in the heliosheath, in response to the pressure of the interstellar medium. It is one of the most-important boundaries in the outer heliosphere.

The termination shock: Physical processes
Advances in Space Research, 1995A brief overview of the physics thought to determine the properties of the heliospheric termination shock is given and the central role of hot interstellar pick-up ions and cosmic rays is emphasized.

Motion of the heliospheric termination shock at high heliographic latitude [PDF]
Space Science Reviews, 1995 We expect the mean distance of the heliospheric termination shock to be greater (smaller) at polar latitudes than at equatorial latitudes, depending on whether the mean dynamic pressure of the solar wind is greater or smaller at high latitudes.

Shock After Arrhythmia Termination
2020A 58-year-old male with a history of congestive heart failure and an ICD comes to clinic after receiving an ICD shock while mowing the lawn. The patient was not symptomatic during the episode. His left ventricular ejection fraction is 25% and he is being treated with appropriate medications including an angiotensin converting enzyme inhibitor and a ...

The solar wind shock termination
Advances in Space Research, 1986Abstract We analyse the possibility that the shock termination of the solar wind should occur at a heliocentric distance of 50 a.u. It is concluded that this is possible if the density of the interstellar medium near the Sun is of the order of 0.5 cm −3 , or the pressure of low energy cosmic rays (less than about 300 MeV/nucleon) is of the order of 6×

Detecting the termination shock and beyond
AIP Conference Proceedings, 1999Based on Voyager 2 observations, a numerical model of the heliosphere, which includes the mutual interaction of the interstellar medium, solar wind plasma, and interstellar hydrogen, is employed to speculate on the possible crossing of the termination shock by the Voyager spacecraft.
