Redefining flux ropes in heliophysics

Frontiers in Astronomy and Space Sciences, 2023
Magnetic flux ropes manifest as twisted bundles of magnetic field lines. They carry significant amounts of solar mass in the heliosphere. This paper underlines the need to advance our understanding of the fundamental physics of heliospheric flux ropes ...

Plasma Dynamics in Low-Electron-Beta Environments

Frontiers in Astronomy and Space Sciences, 2021
Recent in situ measurements by the MMS and Parker Solar Probe missions bring interest to small-scale plasma dynamics (waves, turbulence, magnetic reconnection) in regions where the electron thermal energy is smaller than the magnetic one.

Exclusion of Tiny Interstellar Dust Grains from the Heliosphere [PDF]

, 2009
The distribution of interstellar dust grains (ISDG) observed in the Solar System depends on the nature of the interstellar medium-solar wind interaction.

Solar energetic particle time series analysis with Python

Frontiers in Astronomy and Space Sciences, 2022
Solar Energetic Particles (SEPs) are charged particles accelerated within the solar atmosphere or the interplanetary space by explosive phenomena such as solar flares or Coronal Mass Ejections (CMEs). Once injected into the interplanetary space, they can

Exploring the Properties of the Electron Strahl at 1 AU as an Indicator of the Quality of the Magnetic Connection Between the Earth and the Sun

Frontiers in Astronomy and Space Sciences, 2021
In this report some properties of the electron strahl at 1 AU are examined to assess the strahl at 272 eV as an indicator of the quality of the magnetic connection of the near-Earth solar wind to the Sun.

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.

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.
