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 ...

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.

Analysis of interplanetary solar sail trajectories with attitude dynamics [PDF]

, 2012
We present a new approach to the problem of optimal control of solar sails for low-thrust trajectory optimization. The objective was to find the required control torque magnitudes in order to steer a solar sail in interplanetary space.

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)

Solar Wind Forecasting for Long-term Variations of the Global Heliosphere

The Astrophysical Journal
The large-scale dynamics of the heliosphere is driven by solar activity and variable solar wind (SW) conditions. In situ SW observations inform time-dependent heliosphere modeling efforts but are only available up until the present day, thus restricting ...

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
