Approximation of Daily AMS‐02 Spectra With Machine Learning Methods

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

A future interstellar probe on the dynamic heliosphere and its interaction with the very local interstellar medium: In-situ particle and fields measurements and remotely sensed ENAs

Frontiers in Astronomy and Space Sciences, 2023
The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...

Effect of Supernovae on the Local Interstellar Material

, 2017
A range of astronomical data indicates that ancient supernovae created the galactic environment of the Sun and sculpted the physical properties of the interstellar medium near the heliosphere.

On the Scaling Properties of Magnetic-field Fluctuations through the Inner Heliosphere [PDF]

Astrophysical Journal, 2020
Although the interplanetary magnetic-field variability has been extensively investigated in situ using data from several space missions, newly launched missions providing high-resolution measures and approaching the Sun offer the possibility to study the

CNN‐Based Model for 3D CME Parameter Prediction – A Proof of Concept

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Accurate 3D reconstruction of coronal mass ejections (CMEs) is essential for understanding their propagation and improving space weather forecasts. In this study, we present a proof‐of‐concept deep learning framework that predicts seven parameters from synthetic multi‐view coronagraph images.

SQUARE2: Spacecraft in QUAdrature for Solar Exploration—A Mission Concept for Synergetic Observations of the Sun and Heliosphere

Frontiers in Astronomy and Space Sciences, 2022
SQUARE2 is the acronym for Spacecraft in QUAdrature for solaR Exploration, and is a mission concept for multi-instrumental two-point observations of the Sun and its environment. It stems from the need to have two probes that are systematically in orbital

Solving the Mystery of the Electron Radiation Belt at Uranus: Leveraging Knowledge of Earth's Radiation Belts in a Re‐Examination of Voyager 2 Observations

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Voyager 2 provided the only direct measurement of the radiation environment at Uranus and established the well‐accepted characterization of a system with a weaker ion radiation belt and surprisingly intense electron radiation belt. Recent re‐analysis of the flyby, however, suggests that these observations were not taken during normal solar ...

A Predicted Small and Round Heliosphere [PDF]

, 2018
The shape of the solar wind bubble within the interstellar medium, the so-called heliosphere, has been explored over six decades. As the Sun moves through the surrounding partially-ionized medium, neutral hydrogen atoms penetrate the heliosphere, and ...

Radial intensity gradients of galactic cosmic rays in the heliosphere at solar maximum: 1D no-shock simulation [PDF]

Geofísica Internacional, 2009
We study the spatial distribution of galactic cosmic rays in the heliosphere at solar maximum of cycles 21, 22 and 23, using a one-dimensional no-shock model of the cosmic ray transport equation.

The Heliosphere---Blowing in the Interstellar Wind

, 2013
Measurements of the velocity of interstellar HeI inside of the heliosphere have been conducted over the past forty years. These historical data suggest that the ecliptic longitude of the direction of the interstellar flow has increased at an average rate
