No Stagnation Region before the Heliopause at Voyager 1? Inferences from New Voyager 2 Results [PDF]
, 2021 We present anisotropy results for anomalous cosmic-ray protons in the energy range ~0.5–35 MeV from Cosmic Ray Subsystem (CRS) data collected during calibration roll maneuvers for the magnetometer instrument when Voyager 2 (V2) was in the inner ...

Instability of the heliopause driven by charge exchange interactions [PDF]
, 2014 The stability of the heliopause that separates the tenuous hot magnetized heliosheath plasma from the dense cool local interstellar magnetized plasma is examined using a fully general model that includes all the essential physical processes.

The charge-exchange induced coupling between plasma-gas counterflows in the heliosheath [PDF]
Annales Geophysicae, 2003 Many hydrodynamic models have been presented which give similar views of the interaction of the solar wind plasma bubble with the counterstreaming partially ionized interstellar medium.

Voyager 1 and 2 Observations of a Change in the Nature of Magnetic Fluctuations in the VLISM with Increasing Distance from the Heliopause [PDF]
, 2020 Voyager 2 (V2) crossed the heliopause at 119.0 au on 2018 day 309, after which it observed compressive (longitudinal) magnetic field fluctuations along the average magnetic field direction in the very local interstellar medium (VLISM) at distances from ...

Eos, Transactions American Geophysical Union, 1985 Observations by the Voyager 1 and 2 plasma wave instruments may have provided evidence of the edge of the solar system by “remote sensing.” The two plasma wave receivers detected a weak signal near 3 kHz during late 1983 and early 1984 while the spacecraft were approximately 13 AU (Voyager 2) and 21 AU (Voyager 1) from the sun.

Magnetic Reconnection in the Space Sciences: Past, Present, and Future
Journal of Geophysical Research: Space Physics, Volume 125, Issue 2, February 2020., 2020 Abstract Magnetic reconnection converts, often explosively, stored magnetic energy to particle energy in space and in the laboratory. Through processes operating on length scales that are tiny, it facilitates energy conversion over dimensions of, in some cases, hundreds of Earth radii.

Journal of Physics: Conference Series, 2015 The heliopause (HP) separates the tenuous hot heliosheath plasma from the relatively dense cool magnetized plasma of the local interstellar medium (LISM). Fluid acceleration in the HP region can therefore drive Rayleigh-Taylor-like and Kelvin-Helmholtz- like instabilities.

ON THE ROTATION OF THE MAGNETIC FIELD ACROSS THE HELIOPAUSE [PDF]
The Astrophysical Journal, 2013 There was an expectation that the magnetic field direction would rotate dramatically across the heliopause (HP). This rotation was used as one of the criteria to determine if Voyager 1 (V1) had crossed the HP. Recently the Voyager team concluded that V1 crossed into interstellar space last year (Gurnett et al. 2013).

The structure of the hydrodynamic plasma flow near the heliopause stagnation point [PDF]
, 2010 The plasma flow in the vicinity of the heliopause stagnation point in the presence of the H atom flow is studied. The plasma at both sides of the heliopause is considered to be a single fluid.

Empirical Estimate of the Shape of the Upstream Heliopause from IBEX-Lo Helium Measurements: Preliminary Results [PDF]
, 2017 We present a simplified model of the outer heliosheath to help interpret the observations of interstellar neutral helium by the IBEX-Lo instruments. We assume that the measured particles are composed of the superposition of a primary beam population ...
