In Situ Observations of Interstellar Pickup Ions from 1 au to the Outer Heliosphere
Interstellar pickup ions are an ubiquitous and thermodynamically important component of the solar wind plasma in the heliosphere. These PUIs are born...

Interstellar Neutrals, Pickup Ions, and Energetic Neutral Atoms Throughout the Heliosphere: Present Theory and Modeling Overview
Interstellar neutrals (ISNs), pick-up ions (PUIs), and energetic neutral atoms (ENAs) are fundamental constituents of the heliosphere and its...

Observations of the Outer Heliosphere, Heliosheath, and Interstellar Medium
The Voyager spacecraft have left the heliosphere and entered the interstellar medium, making the first observations of the termination shock,...

Dust in and Around the Heliosphere and Astrospheres
Interstellar dust particles were discovered in situ, in the solar system, with the Ulysses mission’s dust detector in 1992. Ever since, more...

The Structure of the Global Heliosphere as Seen by In-Situ Ions from the Voyagers and Remotely Sensed ENAs from Cassini
The exploration of interplanetary space and our solar bubble, the heliosphere, has made a big leap over the past two decades, due to the...

Turbulence in the Outer Heliosphere
The solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their interaction is governed by complex physical processes and creates...
-
Inhomogeneity in the Local ISM and Its Relation to the Heliosphere
This paper reviews past research and new studies underway of the local interstellar environment and its changing influence on the heliosphere. The...

Oblique and rippled heliosphere structures from the Interstellar Boundary Explorer
Past analysis has shown that the heliosphere structure can be deduced from correlations between long-scale solar wind pressure evolution and...

Theory of Cosmic Ray Transport in the Heliosphere
Modelling the transport of cosmic rays (CRs) in the heliosphere represents a global challenge in the field of heliophysics, in that such a study, if...

The Structure of the Large-Scale Heliosphere as Seen by Current Models
This review summarizes the current state of research aiming at a description of the global heliosphere using both analytical and numerical modeling...

Observations of cross scale energy transfer in the inner heliosphere by Parker Solar Probe
The solar wind, a continuous flow of plasma from the sun, not only shapes the near Earth space environment but also serves as a natural laboratory to...

Galactic Cosmic Rays Throughout the Heliosphere and in the Very Local Interstellar Medium
We review recent observations and modeling developments on the subject of galactic cosmic rays through the heliosphere and in the Very Local...

The Early History of Heliospheric Science and the Spacecraft That Made It Possible
Our understanding of the interaction of the large-scale heliosphere with the local interstellar medium (LISM) has undergone a profound change since...

Future Exploration of the Outer Heliosphere and Very Local Interstellar Medium by Interstellar Probe
A detailed overview of the knowledge gaps in our understanding of the heliospheric interaction with the largely unexplored Very Local Interstellar...

Anomalous Component of Cosmic Rays
The anomalous component of cosmic rays (ACR) in the heliosphere (Fig. 5.1) was discovered in the early 1970s from spacecraft measurements. The ACR...

A possible direct exposure of the Earth to the cold dense interstellar medium 2–3 Myr ago
Cold, dense clouds in the interstellar medium of our Galaxy are 4–5 orders of magnitude denser than their diffuse counterparts. Our Solar System has...

Anomalous Cosmic Rays and Heliospheric Energetic Particles
We present a review of Anomalous Cosmic Rays (ACRs), including the history of their discovery and recent insights into their acceleration and...

Shocks in the Very Local Interstellar Medium
Large-scale disturbances generated by the Sun’s dynamics first propagate through the heliosphere, influence the heliosphere’s outer boundaries, and...
