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 ...

Turbulence in the Outer Heliosphere

Space Science Reviews, 2022
AbstractThe solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their interaction is governed by complex physical processes and creates heliospheric regions with significantly different properties in terms of particle populations, bulk flow and turbulence.

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 Heliosphere and Local Interstellar Medium from Neutral Atom Observations at Energies Below 10 keV. [PDF]

, 2022
As the heliosphere moves through the surrounding interstellar medium, a fraction of the interstellar neutral helium, hydrogen, and heavier species crossing the heliopause make it to the inner heliosphere as neutral atoms with energies ranging from few eV

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.

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.

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.

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 ...
