The Sun as a driver of the inner heliosphere: Modern investigations of fundamental plasma processes [PDF]

Nature Communications
The inner heliosphere serves as a natural laboratory to study fundamental plasma physics. A robust understanding of kinetic processes will fill gaps in our global understanding of the Sun and heliosphere, with applicability to laboratory and ...

Oblique and rippled heliosphere structures from the Interstellar Boundary Explorer [PDF]

Nat Astron, 2022
Past analysis has shown that the heliosphere structure can be deduced from correlations between long-scale solar wind pressure evolution and energetic neutral atom emissions.

Exploring Numerical Correlations: Models and Thermodynamic Kappa [PDF]

Entropy
McComas et al. (2025) introduced a numerical experiment, where ordinary uncorrelated collisions between collision pairs are followed by other, controlled (correlated) collisions, shedding light on the emergence of kappa distributions through particle ...

Whence the interstellar magnetic field shaping the heliosphere? [PDF]

, 2022
Measurements of starlight polarized by aligned interstellar dust grains are used to probe the relation between the orientation of the ambient interstellar magnetic field (ISMF) and the ISMF traced by the ribbons of energetic neutral atoms discovered by ...

Solar Orbiter SWA Observations of Electron Strahl Properties Inside 1 AU

Universe, 2022
The Solar Wind Analyser (SWA) suite on Solar Orbiter includes an Electron Analyser System (SWA-EAS) which is capable of high temporal and angular resolution measurements of solar wind electrons in the energy range ∼1 eV to ∼5 keV.

Turbulence in the Outer Heliosphere

Space Science Reviews, 2022
AbstractThe solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their interaction is governed by complex physical processes and creates heliospheric regions with significantly different properties in terms of particle populations, bulk flow and turbulence.

Ulysses Flyby in the Heliosphere: Comparison of the Solar Wind Model with Observational Data

Universe, 2022
A model capable of reproducing a set of solar wind parameters along the virtual spacecraft orbit out of an ecliptic plane has been developed. In the framework of a quasi-stationary axisymmetric self-consistent MHD model the spatial distributions of ...

A MODEL OF THE HELIOSPHERE WITH JETS [PDF]

The Astrophysical Journal, 2015
An analytic model of the heliosheath (HS) between the termination shock (TS) and the heliopause (HP) is developed in the limit in which the interstellar flow and magnetic field are neglected. The heliosphere in this limit is axisymmetric and the overall structure of the HS and HP are controlled by the solar magnetic field even in the limit in which the

Modulation of Solar Wind Impact on the Earth’s Magnetosphere during the Solar Cycle

Universe, 2022
The understanding of extreme geomagnetic storms is one of the key issues in space weather. Such phenomena have been receiving increasing attention, especially with the aim of forecasting strong geomagnetic storms generated by high-energy solar events ...

Mesoscale Structure in the Solar Wind

Frontiers in Astronomy and Space Sciences, 2021
Structures in the solar wind result from two basic mechanisms: structures injected or imposed directly by the Sun, and structures formed through processing en route as the solar wind advects outward and fills the heliosphere. On the largest scales, solar
