Antiproton modulation in the Heliosphere and AMS-02 antiproton over proton ratio prediction

, 2011
We implemented a quasi time-dependent 2D stochastic model of solar modulation describing the transport of cosmic rays (CR) in the heliosphere. Our code can modulate the Local Interstellar Spectrum (LIS) of a generic charged particle (light cosmic ions ...

Evolving outer heliosphere: Large-scale stability and time variations observed by the Interstellar Boundary Explorer [PDF]

, 2010
The first all-sky maps of Energetic Neutral Atoms (ENAs) from the Interstellar Boundary Explorer (IBEX) exhibited smoothly varying, globally distributed flux and a narrow ribbon of enhanced ENA emissions.

The residence-time of Jovian electrons in the inner heliosphere [PDF]

Astronomy & Astrophysics, 2020
Context. Jovian electrons serve an important role in test-particle distribution in the inner heliosphere. They have been used extensively in the past to study the (diffusive) transport of cosmic rays in the inner heliosphere.

Comparing various multi-component global heliosphere models

, 2007
Modeling of the global heliosphere seeks to investigate the interaction of the solar wind with the partially ionized local interstellar medium. Models that treat neutral hydrogen self-consistently and in great detail, together with the plasma, but that ...

Breathing of the Heliosphere

Astrophysical Journal, 2021
In late 2016, the Interstellar Boundary Explorer (IBEX) observed an enhancement of hydrogen energetic neutral atom (ENA) flux in ∼20° south from the nose direction.

Impact of Inner Heliospheric Boundary Conditions on Solar Wind Predictions at Earth

Space Weather, 2021
Predictions of the physical parameters of the solar wind at Earth are at the core of operational space weather forecasts. Such predictions typically use line‐of‐sight observations of the photospheric magnetic field to drive a heliospheric model.

Warm Breeze from the starboard bow: a new population of neutral helium in the heliosphere

, 2014
We investigate the signals from neutral He atoms observed from Earth orbit in 2010 by IBEX. The full He signal observed during the 2010 observation season can be explained as a superposition of pristine neutral interstellar He gas and an additional ...

Phenomenological Evaluation of the Electron Density‐Based Péclet Number of Near‐Earth Solar Wind Turbulence

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract The electron density‐based Péclet number has been measured for the first time in the solar wind, alongside a measure of the magnetic Reynolds number. The Péclet number is an important characteristic of energy and particle transport. High Péclet numbers indicate that particle advection dominates diffusion of energy.

Time-variability in the Interstellar Boundary Conditions of the Heliosphere: Effect of the Solar Journey on the Galactic Cosmic Ray Flux at Earth

, 2011
During the solar journey through galactic space, variations in the physical properties of the surrounding interstellar medium (ISM) modify the heliosphere and modulate the flux of galactic cosmic rays (GCR) at the surface of the Earth, with consequences ...

Dust in the Local Interstellar Wind [PDF]

, 1999
The gas-to-dust mass ratios found for interstellar dust within the Solar System, versus values determined astronomically for the cloud around the Solar System, suggest that large and small interstellar grains have separate histories, and that large ...
