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 ...

Anisotropies of 40–139 keV Ions Measured beyond the Termination Shock and in the Very Local Interstellar Medium

The Astrophysical Journal
We analyze the count rates of 40–139 keV ions that were measured in situ by the Low Energy Charged Particle instrument on Voyager 1 in order to identify the suprathermal ion anisotropies beyond the termination shock and in the very local interstellar (IS)

The heliosphere-interstellar medium interaction: One shock or two? John D. Richardson M.I.T. [PDF]

, 1997
. The issue of whether a shock forms in the interstellar medium as it approaches the heliopause has not been settled. Observations generally show that the local interstellar medium is slightly supersonic with respect to a stationary (constant distance ...

Kelvin–Helmholtz Instability and Energetic Neutral Atoms in the Heliosphere

The Astrophysical Journal Letters
The Interstellar Mapping and Acceleration Probe (IMAP) mission launched from Earth on 2025 September 24, beginning its commissioning phase as the spacecraft makes its way to Lagrange Point 1.

Evolution of a Pickup Ion Ring-beam Population in Large-scale Interstellar Turbulence and Small-scale Self-generated Waves: Implications for the IBEX Ribbon

The Astrophysical Journal
The secondary energetic neutral atom (ENA) mechanism proposed to explain the ribbon-like enhancement of ENA emission observed by Interplanetary Boundary Explorer (IBEX) involves a pickup ion (PUI) ring-beam population beyond the heliopause. The stability

MAGNETIC FLUX TUBE INTERCHANGE AT THE HELIOPAUSE

The Astrophysical Journal, 2015
The magnetic field measured by Voyager 1 prior to its heliocliff encounter on 2012.65 showed an unexpectedly complex transition from the primarily azimuthal inner-heliosheath field to the draped interstellar field tilted by some 20° to the nominal azimuthal direction.
