Magnetic field spectral analysis in the Heliosheath from Voyagers data [PDF]

, 2016
In 2004 and 2007 the two Voyagers crossed the termination shock entering the heliosheath, where the solar wind is slowed down and interacts with the interstellar medium.

Interstellar Neutral Hydrogen in the Heliosphere: New Horizons Observations in the Context of Models

The Astrophysical Journal Letters
Interstellar neutral (ISN) hydrogen is the most abundant species in the outer heliosheath and the very local interstellar medium (VLISM). Charge-exchange collisions in the outer heliosheath result in filtration, reducing the ISN hydrogen density inside ...

Lyα Absorption in a “Croissant-like” Heliosphere

The Astrophysical Journal
Ly α absorption profiles have been used to detect astrospheres and heliospheric absorption from the hydrogen wall and heliotail. Using magnetohydrodynamic models of the heliosphere, we can compare simulated to observed Ly α profiles to probe the neutral ...

An Investigation of the Evolution of Heliosheath Energetics Using a Pressure Enhancement Event Observed by IBEX

The Astrophysical Journal
During solar cycle 24, an increase in the solar wind (SW) dynamic pressure in late 2014 caused a sharp increase in the heliospheric energetic neutral atom (ENA) flux that was seen by the Interstellar Boundary Explorer (IBEX) at 1 au in late 2016.

Toward Explaining Galactic Cosmic-Ray Modulation in a Dynamic Heliosheath: Transient Structures Seem Dominant and Magnetic Drifts Appear Reduced

The Astrophysical Journal
While traveling through the heliosheath (HS), Voyager 2 observed sustained flux depletions of galactic cosmic rays (GCRs) on scales of months to years.
