Whence the interstellar magnetic field shaping the heliosphere? [PDF]

, 2022
Measurements of starlight polarized by aligned interstellar dust grains are used to probe the relation between the orientation of the ambient interstellar magnetic field (ISMF) and the ISMF traced by the ribbons of energetic neutral atoms discovered by ...

Ulysses Flyby in the Heliosphere: Comparison of the Solar Wind Model with Observational Data

Universe, 2022
A model capable of reproducing a set of solar wind parameters along the virtual spacecraft orbit out of an ecliptic plane has been developed. In the framework of a quasi-stationary axisymmetric self-consistent MHD model the spatial distributions of ...

Modulation of Solar Wind Impact on the Earth’s Magnetosphere during the Solar Cycle

Universe, 2022
The understanding of extreme geomagnetic storms is one of the key issues in space weather. Such phenomena have been receiving increasing attention, especially with the aim of forecasting strong geomagnetic storms generated by high-energy solar events ...

Mesoscale Structure in the Solar Wind

Frontiers in Astronomy and Space Sciences, 2021
Structures in the solar wind result from two basic mechanisms: structures injected or imposed directly by the Sun, and structures formed through processing en route as the solar wind advects outward and fills the heliosphere. On the largest scales, solar

The Electron Structure of the Solar Wind

Frontiers in Astronomy and Space Sciences, 2021
Time-series measurements of the number density ncore and temperature Tcore of the core-electron population of the solar wind are examined at 1 AU and at 0.13 AU using measurements from the WIND and Parker Solar Probe spacecraft, respectively.

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 ...

Turbulence transport throughout the heliosphere [PDF]

, 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 ...

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.
