Improving Predictions of High‐Latitude Coronal Mass Ejections Throughout the Heliosphere

Space Weather, 2020
Predictions of the impact of coronal mass ejections (CMEs) in the heliosphere mostly rely on cone CME models, whose performances are optimized for locations in the ecliptic plane and at 1 AU (e.g., at Earth).

Theoretical Refinements to the Heliospheric Upwind eXtrapolation Technique and Application to in-situ Measurements

Frontiers in Astronomy and Space Sciences, 2022
The large-scale structure and evolution of the solar wind are typically reproduced with reasonable fidelity using three-dimensional magnetohydrodynamic (MHD) models.

What is the heliopause? Importance of magnetic reconnection and measurement requirements

Frontiers in Astronomy and Space Sciences, 2023
We highlight the importance of magnetic reconnection at the heliopause, both as one of the key processes driving the interaction between solar and interstellar media, but also as an element of the definition of the heliopause itself.

Complementary interstellar detections from the heliotail

Frontiers in Astronomy and Space Sciences
The heliosphere is a protective shield around the solar system created by the Sun’s interaction with the local interstellar medium (LISM) through the solar wind, transients, and interplanetary magnetic field.

Turbulence transport throughout the heliosphere

, 2007
We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, the energy per unit mass, the ...

Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection [PDF]

, 2008
We describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation.

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 ...

Boundary conditions of the heliosphere [PDF]

Journal of Geophysical Research: Space Physics, 2003
Radiative transfer equilibrium models of nearby interstellar matter (ISM) are required to determine the boundary conditions of the heliosphere from astronomical observations of nearby stars. These models are also constrained by data on the ISM inside of the solar system, including pickup ion, anomalous cosmic rays, and in situ Heo data.

Heating the outer heliosphere by pickup protons

, 2004
There is a growing body of literature that demonstrates the ability of a turbulent cascade within the solar wind to heat the thermal protons. Several sources of energy are required to accomplish the observed heating.

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.
