Whole Heliosphere Interval: Overview of JD16

, 2009
The Whole Heliosphere Interval is an international observing and modeling effort to characterize the three-dimensional interconnected solar-heliospheric-planetary system, i.e., the “heliophysical” system.

Collisional thermalization of minor ions in the solar wind

Frontiers in Astronomy and Space Sciences
IntroductionAs the solar wind transits through the heliosphere, Coulomb collisions among constituent particles drives it toward local thermodynamic equilibrium. Prior studies of ion collisions in the solar wind have focused on the two most abundant solar

A Robust Empirical Relationship Between Speed and Turbulence Energy in the Near‐Earth Solar Wind

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The connection between turbulence and solar‐wind acceleration, long known in space physics, is further developed in this study by establishing a robust empirical law that relates the bulk‐flow speed to the magnetohydrodynamic‐scale fluctuation energy in the plasma. The model is based on analysis of 25 years of near‐Earth observations by NASA's

Nanodust in the Heliosphere

Journal of Physics: Conference Series, 2019
Abstract The NASA Parker Solar Probe and the ESA Solar Orbiter will explore the source region of the solar wind within 20 solar radii. Their unprecedented in-situ measurements are also expected to shed light on the nature of the F-corona and the existence of a halo of nanodust.

Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

Exclusion of Tiny Interstellar Dust Grains From the Heliosphere [PDF]

, 2010
The distribution of interstellar dust grains (ISDG) observed in the Solar System depends on the nature of the interstellar medium‐solar wind interaction.

Analytical Model Nonequilibrium Inhomogeneous Plasma of the Heliosphere

, 2021
We prove that a nonequilibrium inhomogeneous giant gas discharge is realized in the heliosphere with huge values of the parameter E/N, which determines the temperature of electrons.

Comprehensive Characterization of Water Group Ion Composition and Distributions in Saturn's Magnetosphere With Cassini Plasma Spectrometer Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Saturn's magnetosphere is continuously supplied with neutrals from the Enceladus plume and the icy rings, which undergo ionization and charge‐exchange to form a complex water‐group plasma environment. While the Cassini Plasma Spectrometer (CAPS) instrument has provided extensive compositional information, detailed separation of individual ...

The Heliosphere as Seen in TeV Cosmic Rays

, 2016
Measurements from several cosmic-ray air shower experiments reveal that the anisotropy of TeV cosmic-ray flux does not agree with a dipole pattern commonly expected from the Compton–Getting effect or from the diffusion of cosmic rays in Galactic magnetic

Earth's Mesosphere During Possible Encounters With Massive Interstellar Clouds 2 and 7 Million Years Ago

Geophysical Research Letters
Our solar system's path has recently been shown to potentially intersect dense interstellar clouds 2 and 7 million years ago: the Local Lynx of Cold Cloud and the edge of the Local Bubble.
