The spacecraft Voyager 1 is at a distance greater than 85 au from the Sun, in the vicinity of the termination shock that marks the abrupt slowing of the supersonic solar wind and the beginning of the extended and unexplored distant heliosphere. This shock is expected to accelerate ‘anomalous cosmic rays’, as well as to re-accelerate Galactic cosmic rays and low-energy particles from the inner Solar System. Here we report a significant increase in the numbers of energetic ions and electrons that… 

The Origin of Low-energy Anomalous Cosmic Rays at the Solar-wind Termination Shock

We address the origin of the enhancement of ∼40 keV to 5 MeV ions at the solar wind termination shock. Using self-consistent two-dimensional hybrid simulations (kinetic proton, fluid electron) of a

The Heliospheric Termination Shock

The heliospheric termination shock is a vast, spheroidal shock wave marking the transition from the supersonic solar wind to the slower flow in the heliosheath, in response to the pressure of the

Acceleration of low-energy ions at the termination shock of the solar wind

The Voyager 1 investigators have reported that the spacecraft crossed the termination shock of the solar wind at 94 AU from the Sun. The intensity of low-energy ions (≲3 MeV nucleon-1) increases

Galactic cosmic ray distribution in the simplest model of termination shock near the heliospheric boundaries

The termination shock at the heliospheric boundary is simulated in terms of a two-layer turbulent medium for which the average radial component of solar wind velocity is nonzero inside the

The re-acceleration of galactic electrons at the heliospheric termination shock

Observations by the Voyager spacecraft in the outer heliosphere presented several challenges for the paradigm of diffusive shock acceleration (DSA) at the solar wind termination shock (TS). In this

A heliospheric hybrid model: hydrodynamic plasma flow and kinetic cosmic ray transport

In this paper we present a new five particle species hybrid model for calculating cosmic ray particle transport and acceleration in a dynamic heliospheric environment. In particular the effects of

Acceleration of galactic electrons at the solar wind termination shock and Voyager 1 observations

Diffusive shock acceleration (DSA), as an acceleration process for Galactic electrons at the solar wind termination shock (TS), is investigated with a comprehensive numerical model which incorporates

Cosmic ray energy changes in the heliosphere: Effects of the termination shock and heliosheath

Adiabatic energy losses form a well‐understood part of cosmic ray modulation in the heliosphere. However, shock acceleration at the solar wind termination shock and the modulation in the heliosheath

Effects of the solar wind termination shock and heliosheath on theheliospheric modulation of galactic and anomalous Helium

Abstract. 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



The gradient of galactic cosmic rays at the solar-wind termination shock

We report on a study of the expected spatial variation of the galactic cosmic-ray intensity in the outer heliosphere, in the vicinity of the solar-wind termination shock. Model simulations which

Composition of Anomalous Cosmic Rays and Other Heliospheric Ions

Interstellar pickup ions accelerated by the termination shock of the solar wind dominate the anomalous cosmic-ray (ACR) intensities observed by the Voyager spacecraft in the outer heliosphere. Using

Anomalous Cosmic Rays at a Termination-Shock Crossing

We consider the response of anomalous cosmic rays to transient radial incursions of the solar-wind termination shock. We find that the anomalouscosmic-ray spectrum and anisotropy has a temporal

Cosmic ray investigation for the Voyager missions; energetic particle studies in the outer heliosphere—And beyond

A cosmic-ray detector system (CRS) has been developed for the Voyager mission which will measure the energy spectrum of electrons from ≈3–110 MeV and the energy spectra and elemental composition of

Giant transient decreases of cosmic rays in the outer heliosphere in September 1991

Large transient decreases over 20 percent were observed above 70 MeV cosmic ray intensity in September 1991, at the three spacecraft, V1, V2, and P10, in the outer heliosphere between 35 and 53 AU.

Heliospheric “FALTS”: Favored Acceleration Locations at the Termination Shock

The standard explanation for Anomalous Cosmic Rays requires strong energization at the heliospheric termination shock. However, the tightly wrapped magnetic spiral in the outer heliosphere produces a

Radio Emission from the Heliopause Triggered by an Interplanetary Shock

A strong heliospheric radio emission event has been detected by Voyagers 1 and 2 in the frequency range of 2 to 3 kilohertz and is believed to have been generated at or near the heliopause by an interplanetary shock that originated during a period of intense solar activity in late May and early June 1991.

Acceleration of interstellar pickup H+ and He+ as well as of solar wind protons and alpha particles has been observed on Ulysses during the passage of a corotating interaction region (CIR) at ∼4.5

Cosmic ray drift, shock wave acceleration and the anomalous component of cosmic rays

A model of the anomalous component of the quiet-time cosmic ray flux is presented in which ex-interstellar neutral particles are accelerated continuously in the polar regions of the solar-wind

Pick-up ion acceleration at the termination shock and the post-shock pick-up ion energy distribution

It is discussed since quite some time in the literature that the solar wind termination shock may act as an efficient particle accelerator though the underlying physics of injecting particles into
