Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract In this work we investigate how ionization from Galactic Cosmic Rays (GCRs) can affect aerosol nucleation on Neptune and discuss potential implications for the observed brightness variations that appear to follow the solar cycle. We calculate the planetary vertical cutoff rigidity for Neptune based on the O8 ${\mathrm{O}}_{8}$ magnetic field ...

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research
Reviews of Geophysics, Volume 64, Issue 3, September 2026.Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

The Heliosphere as Seen in TeV Cosmic Rays [PDF]
, 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

Uranus's Highly Nonaxisymmetric Magnetopause and Its Impact on Magnetic Reconnection
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract Mass and energy fluxes from the solar wind can access a planet's magnetosphere through dayside magnetic reconnection. The plasma and magnetic field conditions on either side of the magnetopause determine whether reconnection is suppressed. However, magnetosheath conditions are sensitive to the shape of the magnetopause, and deviations from ...

The Heliosphere through the Solar Activity Cycle
, 2008 Understanding how the Sun changes though its 11-year sunspot cycle and how these changes affect the vast space around the Sun – the heliosphere – has been one of the principal objectives of space research since the advent of the space age.

Adapted Empirical Modeling of Near‐Sun Solar‐Wind Speeds for Use in Ensemble Forecasts
Space Weather, Volume 24, Issue 9, September 2026.Abstract Solar wind science and forecasting relies on empirical relations between modeled coronal magnetic‐field structure—particularly flux‐tube expansion and distance to coronal hole boundary—and solar‐wind speed. There is lots of uncertainty in these relations, creating large uncertainties in the inner‐boundary conditions to heliospheric models ...

Global MHD Modeling of the Solar Corona and Inner Heliosphere for the Whole Heliosphere Interval
, 2009 With the goal of understanding the three-dimensional structure of the solar corona and inner heliosphere during the “Whole Heliosphere Interval” (WHI), we have developed a global MHD solution for Carrington rotation (CR) 2068.

Connection of Turbulence with Polytropic Index in the Solar Wind Proton Plasma
Entropy, 2019 This paper improves our understanding of the interplay of the proton plasma turbulent heating sources of the expanding solar wind in the heliosphere. Evidence is shown of the connections between the polytropic index, the rate of the heat absorbed by the ...
