What Defines Stationarity in Space Plasmas

The Astrophysical Journal
Starting from the concept of entropy defect in thermodynamics, we construct the entropy formulation of space plasmas, and then use it to develop a measure of their stationarity.

The effect of a dynamic inner heliosheath thickness on cosmic-ray modulation

, 2015
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied over different polarity cycles by computing 2.5 GV proton intensities using a two-dimensional, time-dependent modulationmodel.

Fluctuations Driven by Multicomponent Pickup Ion Distributions in the Outer Heliosheath

The Astrophysical Journal
The stability of a realistic multicomponent pickup ion (PUI) velocity distribution derived from a global model of neutral atoms in the heliosphere, which treats hydrogen and helium atoms self-consistently and includes equations for electrons and helium ...

Four-fluid model and numerical simulations of magnetic structures in the heliosheath

, 2009
The first part of this paper extends the three-fluid model of Avinash & Zank for magnetic structures in the heliosheath to a four-fluid model consisting of electrons, pick-up ions (PUIs), solar wind ions (SWIs), and neutral hydrogen.

Analysis of Voyager Observed High-Energy Electron Fluxes in the Heliosheath Using MHD Simulations

, 2011
The Voyager spacecraft (V1 and V2) observed electrons of 6-14 MeV in the heliosheath which showed several incidences of flux variation relative to a background of gradually increasing flux with distance from the Sun.

An Anisotropic Plasma Model of the Heliospheric Interface

The Astrophysical Journal
We present a pioneering model of the interaction between the solar wind and the surrounding interstellar medium that includes the possibility of different pressures in directions parallel and perpendicular to the magnetic field.
