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

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.

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.

A MODEL OF THE HELIOSPHERE WITH JETS [PDF]
The Astrophysical Journal, 2015 An analytic model of the heliosheath (HS) between the termination shock (TS) and the heliopause (HP) is developed in the limit in which the interstellar flow and magnetic field are neglected. The heliosphere in this limit is axisymmetric and the overall structure of the HS and HP are controlled by the solar magnetic field even in the limit in which the

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 ...
