On the electron temperature downstream of the solar wind termination shock [PDF]
Annales Geophysicae, 2013 In this paper we study the temperatures of electrons convected with the solar wind to large solar distances and finally transported over the solar wind termination shock. Nearly nothing, unless at high energies in the cosmic ray regime, is known about

The heliospheric modulation of cosmic ray protons during increased solar activity: effects of the position of the solar wind termination shock and of the heliopause [PDF]
Annales Geophysicae, 2005 The effects on the modulation of cosmic ray protons of different positions for the solar wind termination shock and for the heliopause are illustrated for moderate solar maximum conditions.

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.

A kinetic description of the dissipative quasi-parallel solar wind termination shock
Astronomy and Astrophysics, 2008 Context. As a special case of astrophysical MHD shock waves, the solar wind termination shock is typically treated using the MHD jump conditions as they have been determined by Rankine and Hugoniot.

Challenges to cosmic ray modeling: From beyond the solar wind termination shock
Advances in Space Research, 2008 Voyager 1 crossed the solar wind termination shock on December 16, 2004 at a distance of 94 AU from the Sun, to become the first spacecraft to explore the termination shock region and to enter the heliosheath, the final heliospheric frontier.

The multi-fluid pressures downstream of the solar wind termination shock
Astronomy and Astrophysics, 2013 In this paper we consider a multi-fluid plasma that describes the upstream solar wind at its passage over the solar wind termination shock. In one respect, the plasma at the shock reacts like a joint fluid that is described by a single compression ratio.

Breathing of heliospheric structures triggered by the solar-cycle activity [PDF]
Annales Geophysicae, 2003 Solar wind ram pressure variations occuring within the solar activity cycle are communicated to the outer heliosphere as complicated time-variabilities, but repeating its typical form with the activity period of about 11 years.

Magnetic Fields In The Termination Shock, Heliosheath And Solar Wind
AIP Conference Proceedings, 2008 This paper will discuss recent magnetic field observations of the termination shock (TS), heliosheath (HSH), and supersonic solar wind (SW) made by Voyager 1 (V1) and Voyager 2 (V2).

Reforming perpendicular shocks in the presence of pickup protons: initial ion acceleration [PDF]
Annales Geophysicae, 2005 Acceleration processes associated with the heliospheric termination shock may provide a source of anomalous cosmic rays (ACRs). Recent kinetic simulations of supercritical, quasi-perpendicular shocks have yielded time varying shock solutions that ...

Interaction of Inner Heliosheath Ions with Electromagnetic Ion Cyclotron Waves
The Astrophysical Journal, 2023 Inner heliosheath (IHS) ions are expected to be exposed to various waves, shocks, and turbulence, which can affect ion distributions and thus their charge-exchange rates with interstellar neutral atoms.
