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)

Energetic Neutral Atom Fluxes from the Voyager 1 and 2 Directions

The Astrophysical Journal
IBEX observes a globally distributed energetic neutral atom (ENA) flux from the heliosheath and very local interstellar medium (VLISM). Over a 14 yr period, Voyager 1 and Voyager 2 traversed the heliosheath from the termination shock to the heliopause ...

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.

Inferring the Interstellar Magnetic Field Direction from Energetic Neutral Atom Observations of the Heliotail

The Astrophysical Journal Letters
Determining the magnitude and direction of the interstellar magnetic field ( B _ISM ) is a long-standing problem. To date, some methods to infer the direction and magnitude have utilized best-fit models to the positions of the termination shock and ...

The Passage of the Solar System through the Edge of the Local Bubble

The Astrophysical Journal
The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr ^−1 , making the conditions outside the solar system vary with time over millions of years.

Signatures of Reconnection and a Split Heliospheric Tail in High-energy Energetic Neutral Atoms

The Astrophysical Journal
The shape of the heliosphere, regarded as comet-like since the 1960s, has recently been the subject of intense debate in the last decade. There is disagreement as to whether the heliospheric tail extends to ∼10,000 au in a comet-like shape or if it 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 ...
