Characterization of Small Flux Ropes Using Juno Spacecraft Cruise-phase Data

open access: yesThe Astrophysical Journal
In this study, we utilize magnetic field data from the Juno mission’s cruise phase to visually identify and analyze 338 interplanetary small flux ropes (SFRs) across a heliocentric distance range of 1–5.5 au.

Probing the magnetic topology of coronal mass ejections by means of Ulysses/HI-SCALE energetic particle observations [PDF]

open access: yesAnnales Geophysicae, 2000
In this work, solar flare energetic particle fluxes (Ee ≥ 42 keV) observed by the HI-SCALE instrument onboard Ulysses, a spacecraft that is probing the heliosphere in 3-D, are utilized as diagnostics of the large-scale structure and topology of

Simulations of Electron Acceleration at Collisionless Shocks: The Effects of Surface Fluctuations [PDF]

open access: yes, 2006
Energetic electrons are a common feature of interplanetary shocks and planetary bow shocks, and they are invoked as a key component of models of nonthermal radio emission, such as solar radio bursts.

Interplanetary Magnetic Field Curvature and Its Role in Particle Acceleration: Magnetospheric Multiscale and Solar Orbiter Observations

open access: yesThe Astrophysical Journal
The curvature of the magnetic field plays a crucial role in magnetic confinement, magnetic reconnection, particle heating, and acceleration. Though the magnetic field curvature has been sufficiently investigated in the terrestrial magnetosheath, there is

Modelling interplanetary CMEs using magnetohydrodynamic simulations [PDF]

open access: yesAnnales Geophysicae, 2002
The dynamics of Interplanetary Coronal Mass Ejections (ICMEs) are discussed from the viewpoint of numerical modelling. Hydrodynamic models are shown to give a good zero-order picture of the plasma properties of ICMEs, but they cannot model the ...

A Fokker–Planck Framework for Studying the Variability of the Magnetic Field Direction in the Alfvénic Streams of the Solar Wind

open access: yesThe Astrophysical Journal Letters
Turbulent rotations of the magnetic field vector are observed in the Alfvénic streams of the solar wind where the magnetic field strength remains close to a constant. They can lead to reversals of the radial magnetic field component or switchbacks. It is

A Global Magnetic Topology Model for Magnetic Clouds. V

open access: yesThe Astrophysical Journal
Magnetic clouds (MCs) are large-scale magnetic structures in the solar wind whose internal physical processes remain only partially understood. In this work, we present an extended analytical model of MCs that simultaneously describes the magnetic field,

Influence of Intermittency on the Energy Transfer Rate of Solar Wind Turbulence

open access: yesThe Astrophysical Journal Letters, 2023
The intermittency in the solar wind turbulence manifests itself in the anisotropic scaling due to the anisotropic spectral index and the intermittent level based on the extended P model. However, the influence of intermittency on the energy transfer rate

Solar Sector Structure

open access: yes, 2015
The interplanetary magnetic field near has a characteristic "sector" structure that reflects its polarity relative to the solar direction. Typically we observe large-scale coherence in these directions, with two or four "away" or "towards" sectors per ...
