On the importance of investigating CME complexity evolution during interplanetary propagation

Frontiers in Astronomy and Space Sciences, 2022
This perspective paper brings to light the need for comprehensive studies on the evolution of interplanetary coronal mass ejection (ICME) complexity during propagation. To date, few studies of ICME complexity exist.

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

, 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.

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.

Suprathermal Electron Acceleration Comparison of the Venusian and Terrestrial Bow Shocks

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract We study suprathermal electron acceleration at the Venusian bow shock using the Parker Solar Probe gravity assists and the Venus Express spacecraft mission. The acceleration is classified by measuring the maximum energy and the power‐law spectral slope (index) of the electron phase space density immediately downstream of the shocks for ...

Cosmic-Ray Diffusion Coefficients throughout the Inner Heliosphere from a Global Solar Wind Simulation

, 2017
We use a three-dimensional magnetohydrodynamic simulation of the solar wind to calculate cosmic-ray diffusion coefficients throughout the inner heliosphere (2R⊙ - 3au).

The Structure of the Large-Scale Heliosphere as Seen by Current Models. [PDF]

, 2022
This review summarizes the current state of research aiming at a description of the global heliosphere using both analytical and numerical modeling efforts, particularly in view of the overall plasma/neutral flow and magnetic field structure, and its ...

Using hydrogen energetic neutral atoms to study the heliosphere [PDF]

, 2021
The interaction between the solar wind and the partially ionized gas of the local interstellar medium (ISM) creates a bubble known as the heliosphere. Classically, the shape of the heliosphere has been regarded as comet-like, with a long tail pointed in ...

Dynamical Solar Wind Forecasting Using In Situ Solar Wind Speed Observations

Space Weather, Volume 24, Issue 11, November 2026.
Abstract Accurate prediction of the ambient solar wind at Earth is a key requirement for space‐weather forecasting but is limited by uncertainties in coronal boundary conditions and, to a lesser extent, heliospheric transport. We present a quantitative assessment of a solar wind forecast that uses near‐Earth in situ solar wind observations to estimate ...

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 ...
