An Anisotropic Plasma Model of the Heliospheric Interface

The Astrophysical Journal
We present a pioneering model of the interaction between the solar wind and the surrounding interstellar medium that includes the possibility of different pressures in directions parallel and perpendicular to the magnetic field.

Turbulence in the Heliosheath: spectral analysis from Voyager 1 and 2 data [PDF]

, 2015
The Voyager 2 spacecraft is traveling through the heliosheath, the outermost layer in heliosphere where the solar wind is slowed by the interstellar gas, while Voyager 1 has entered the local interstellar medium.

Four-fluid model and numerical simulations of magnetic structures in the heliosheath

, 2009
The first part of this paper extends the three-fluid model of Avinash & Zank for magnetic structures in the heliosheath to a four-fluid model consisting of electrons, pick-up ions (PUIs), solar wind ions (SWIs), and neutral hydrogen.

On the Acceleration Site of Anomalous Cosmic Rays: Voyager 2 Observations of Their Anisotropy in the Heliosheath

The Astrophysical Journal
We present the diffusive flow anisotropy vector components for ∼0.5–35 MeV anomalous cosmic-ray (ACR) protons observed during Voyager 2 roll maneuvers for the magnetometer instrument in the inner heliosheath.

Termination Shock Particle Streaming Upstream at New Horizons

The Astrophysical Journal Letters
A couple years before Voyager 1 and Voyager 2 (V2) crossed the termination shock (TS), instruments on board both spacecraft observed high intensities of accelerated termination shock particles (TSPs) beaming in opposite directions.

Search for the heliosheath with Voyager 1 magnetic field measurements [PDF]

, 2003
The magnetic field measured by Voyager 1 (V1) near 85 AU from 2002.0 to 2003.17 has the expected properties for the heliospheric magnetic field at that distance and epoch of the solar cycle.

Exploring the Complex Heliotail Boundary by an Extended Level Set Approach

The Astrophysical Journal Letters
There is an ongoing debate regarding the shape of the heliotail. Studies have shown that the heliotail may be “comet-like,” extending for thousands of au. Some previous works defined the heliopause using magnetohydrodynamic variables, which only serve as
