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.

Plasma flows in the heliosheath [PDF]
Geophysical Research Letters, 2009 Voyager 2 is making the first plasma measurements in the heliosheath. The radial flow speeds in the heliosheath vary between 80 and 200 km/s with an average speed of 138 km/s. The flow in the T (azimuthal) direction is fairly constant and averages about 48 km/s; the flow direction is consistent with flow away from the heliospheric nose.

Mirror and Firehose Instabilities in the Heliosheath [PDF]
The Astrophysical Journal, 2008 We investigate the nature of the heliosheath plasma behind the termination shock across which jump relations in anisotropic MHD are formulated. Along side analytical results for downstream parameters in the strictly parallel and perpendicular cases we numerically solve the Rankine-Hugoniot relations for arbitrary shock angle and strength. We then focus

Unexpected sites of efficient stochastic acceleration in the inner heliosheath [PDF]
Annales Geophysicae, 2007 Up until the recent past, it was generally believed that the solar wind termination shock (TS) is the favourite site to accelerate ions from the keV- to the MeV- energy levels by means of Fermi-1 processes.

PLASMA NEAR THE HELIOSHEATH: OBSERVATIONS AND INTERPRETATIONS [PDF]
The Astrophysical Journal, 2010 Voyager 2 (V2) has observed heliosheath plasma since 2007 August. The plasma flux decreases by 25% before the termination shock (TS), then, as V2 moved into the heliosheath, the plasma density, temperature, and flux all decreased by an additional factor of 2. We suggest three effects combine to cause these decreases.

Effects of the solar wind termination shock and heliosheath on theheliospheric modulation of galactic and anomalous Helium [PDF]
Annales Geophysicae, 2004 The interest in the role of the solar wind termination shock and heliosheath in cosmic ray modulation studies has increased significantly as the Voyager 1 and 2 spacecraft approach the estimated position of the solar wind termination shock.

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
