The Effects of Turbulence on Heliosheath Ions and Implications for Energetic Neutral Atoms

The Astrophysical Journal
The distribution of ions in the heliosheath—the region between the heliospheric termination shock and the heliopause—is important for understanding remote observations of energetic neutral atoms (ENAs).

Large-scale Field-aligned Flows in the Heliosheath

The Astrophysical Journal
We use a state-of-the-art 3D MHD simulation to show that large-scale thermal pressure gradients in the heliosheath drive suprathermal particles (pickup ions with 1–5 keV) to stream along magnetic field lines faster than the cold bulk solar wind.

The Role of Pickup Ions in the Interaction of the Solar Wind with the Local Interstellar Medium. II. Effects of Solar Cycle

The Astrophysical Journal
We investigate the role of pickup ions (PUIs) in the interaction of a periodically varying solar wind (SW) with the local interstellar medium (LISM).

Consequences of Hot Electrons for the Structure of the Outer Heliosphere

The Astrophysical Journal
The temperature of electrons is largely unknown in the outer heliosphere because there is a gap in Voyager measurements from ∼3 eV to 22 keV. Most models assume that the electrons have the same temperature as the bulk cold thermal solar wind (10 ^4 K ...

INTERSTELLAR MAGNETIC FIELD SURROUNDING THE HELIOPAUSE

The Astrophysical Journal, 2010
This paper presents a three-dimensional analytical solution, in the limit of very low plasma β-ratio, for the distortion of the interstellar magnetic field surrounding the heliopause. The solution is obtained using a line dipole method that is the integration of point dipole along a semi-infinite line; it represents the magnetic field caused by the ...
