Global Asymmetry of the Heliosphere [PDF]

, 2006
Opher et al. 2006 showed that an interstellar magnetic field parallel to the plane defined by the deflection of interstellar hydrogen atoms can produce a north/south asymmetry in the distortion of the solar wind termination shock.

VARIABILITY OF PLASMA IN THE HELIOSHEATH [PDF]

The Astrophysical Journal, 2011
The heliosheath is the shocked solar wind between the termination shock and the heliopause. Plasma properties are highly variable in this region, with factor-of-two variations of density and thermal speed on timescales from tens of minutes to hours to days.

Effects of a Local Interstellar Magnetic Field on Voyager 1 and 2 Observations [PDF]

, 2006
We show that that an interstellar magnetic field can produce a north/south asymmetry in solar wind termination shock. Using Voyager 1 and 2 measurements, we suggest that the angle $\alpha$ between the interstellar wind velocity and magnetic field is $30^{

Turbulence in the Outer Heliosheath

The Astrophysical Journal, 2018
Abstract We present in situ observations of magnetic turbulence in the draped interstellar magnetic field measured by Voyager 1 during an undisturbed interval from 2015.3987 to 2016.6759 confirming the existence of the turbulence observed previously from 2013.3593 to 2014 ...

MAGNETIC FLUX CONSERVATION IN THE HELIOSHEATH [PDF]

The Astrophysical Journal, 2012
Voyager 1(V1) and Voyager 2(V2) have observed heliosheath plasma since 2005 December and 2007 August, respectively. The observed speed profiles are very different at the two spacecrafts. Speeds at V1 decreased to zero in 2010 while the average speed at V2 is a constant 150 km s{sup -1} with the direction rotating tailward. The magnetic flux is expected

The downwind hemisphere of the heliosphere: Eight years of IBEX-Lo observations [PDF]

, 2017
We present a comprehensive study of energetic neutral atoms (ENAs) of 10 eV to 2.5 keV from the downwind hemisphere of the heliosphere. These ENAs are believed to originate mostly from pickup protons and solar wind protons in the inner heliosheath.

Solar ions in the heliosheath: a possible new source of heavy neutral atoms [PDF]

, 2006
We show that multiply ionized coronal C, N, O, Mg, Si, S ions carried by the solar wind and neutralized by consecutive electron captures from neutral interstellar atoms constitute an important new source of neutral atoms in the inner heliosheath, with ...

Interplanetary coronal mass ejection observed at STEREO‐A, Mars, comet 67P/Churyumov‐Gerasimenko, Saturn, and New Horizons en route to Pluto: Comparison of its Forbush decreases at 1.4, 3.1, and 9.9 AU

Journal of Geophysical Research: Space Physics, Volume 122, Issue 8, Page 7865-7890, August 2017., 2017
Abstract We discuss observations of the journey throughout the Solar System of a large interplanetary coronal mass ejection (ICME) that was ejected at the Sun on 14 October 2014. The ICME hit Mars on 17 October, as observed by the Mars Express, Mars Atmosphere and Volatile EvolutioN Mission (MAVEN), Mars Odyssey, and Mars Science Laboratory (MSL ...

Cosmic ray energy changes at the termination shock and in the heliosheath [PDF]

, 2006
Voyager 1 crossed the termination shock of the solar wind in December 2004 at 94 AU and currently measures the cosmic ray intensity in the heliosheath. To better understand this modulation region beyond the shock, where adiabatic energy changes should be

Plasma and Flows in the Heliosheath

Journal of Physics: Conference Series, 2015
Voyager 2 (V2) is now 20 AU deep into the heliosheath; if the heliosheath width were similar to that in the Voyager 1 (V1) direction, then V2 is 2/3 of the way to the heliopause. We present recent V2 observations, compare with observations from V1, and compare with model predictions.
