Modelling of low-energy galactic electrons in the heliosheath
Advances in Space Research, 2011 The modulation of cosmic ray electrons in the heliosphere plays an important role in improving our understanding and assessment of the processes applicable to low-energy galactic electrons.

The Solar Wind in the Outer Heliosphere and Heliosheath
Space Science Reviews, 2011 The solar wind environment has a large influence on the transport of cosmic rays. This chapter discusses the observations of the solar wind plasma and magnetic field in the outer heliosphere and the heliosheath.

Plasma temperature distributions in the heliosheath [PDF]
Geophysical Research Letters, 2008 Voyager 2 crossed the termination shock (TS) in August 2007 and began observations of the heliosheath. We present the first 400 days of heliosheath plasma data and propose a consistent picture of the energy flow across the TS. Roughly 15% of the plasma flow energy lost at the shock heats the thermal ions and most of the rest of this energy heats the ...

Interstellar hydrogen ionization in the heliosheath [PDF]
Journal of Geophysical Research: Space Physics, 2015 AbstractThe expanding solar wind plasma undergoes a shock transition at the interstellar boundary of the solar system and fills the inner heliosheath, the region between the termination shock and the heliopause. The nonequilibrium heliosheath plasma is a main source of energetic neutral atoms that allow remote probing of the heliospheric interface ...

AIP Conference Proceedings, 2010
This paper describes recent results from Voyager 2 in the heliosheath (HSh). The speed has been constant across the HSh. The density and temperature have decreased, probably due both to a decrease in solar output and deflection of plasma toward the heliotail.

Cassini ENA images of the heliosheath and Voyager “ground truth”: Thickness of the heliosheath
AIP Conference Proceedings, 2012Cassini/INCA (Ion and Neutral Camera) ENA images of the heliosheath, when combined with the “ground truth” of in situ measurements of ion intensities throughout the heliosheath obtained by Voyager/LECP (Low Energy Charged Particle Experiment), allow us to estimate a thickness parameter (L) along the two lines of sight (LOS) to the Voyager 1/2 ...

Magnetic fields in the heliosheath
AIP Conference Proceedings, 2006We review observations of the magnetic field made by Voyager 1 in the heliosheath from DOY 351, 2004 to 125, 2005, and we discuss their significance in regard to the structure and dynamics of the heliosheath. The probability distribution of hourly averages of B in the heliosheath is a Gaussian distribution.

Cosmic rays in the dynamic heliosheath
Advances in Space Research, 2008Cosmic ray modulation in the outer heliosphere is discussed from a modeling perspective. Emphasis is on the transport and acceleration of these particles at and beyond the solar wind termination shock in the inner heliosheath region and how this changes over a solar cycle.

Mirror Modes in the Heliosheath
AIP Conference Proceedings, 2011Mirror mode (MM) structures are identified in the Voyager 1 heliosheath magnetic field data. Their characteristics are: 1) quasiperiodic structures with a typical scale size of ∼57 ρp (proton gyroradii), 2) little or no angular changes across the structures (∼3° longitude and ∼3° latitude), and 3) a lack of sharp boundaries at the magnetic dip edges ...

Planetary and Space Science, 2002
Abstract This paper is an introduction to the topic of stellarsheaths that are formed due to the interaction of stellar winds and interstellar gas flow. Heliosheath formation and possible methods of its detection are discussed in detail. This invited talk was presented at the 2000 Antalya Turkey Conference on the problems of magnetosheaths in the ...
