Selected solar wind parameters at 1 AU through two solar activity cycles [PDF]

open access: yesAnnales Geophysicae, 1994
In situ measurements of the solar wind largely cover more than two solar magnetic activity cycles, namely 20 and 21. This is a very appealing opportunity to study the influence of the activity cycle on the behaviour of the solar wind parameters.

Solar-wind control of plasma sheet dynamics [PDF]

open access: yesAnnales Geophysicae, 2015
The purpose of this study is to quantify how solar-wind conditions affect the energy and plasma transport in the geomagnetic tail and its large-scale configuration. To identify the role of various effects, the magnetospheric data were sorted according

EISCAT measurements of the solar wind [PDF]

open access: yesAnnales Geophysicae, 1996
EISCAT observations of interplanetary scintillation have been used to measure the velocity of the solar wind at distances between 15 and 130 R⊙ (solar radii) from the Sun. The results show that the solar wind consists of two distinct components,

Quantifying the Energy Budget in the Solar Wind from 13.3 to 100 Solar Radii

open access: yesThe Astrophysical Journal, 2023
A variety of energy sources, ranging from dynamic processes, such as magnetic reconnection and waves, to quasi-steady terms, such as plasma pressure, may contribute to the acceleration of the solar wind.

SPECTRUM OF THE INTERPLANETARY PLASMA TURBULENCE AT A DISTANCE FROM THE SUN GREATER THAN 1 AU [PDF]

open access: yesRadio Physics and Radio Astronomy, 2016
Purpose: Making analysis of variations of fast and slow solarwind parameters at distances from the Sun of about 1 AU and more. Design/methodology/approach: The method of Feynman pathintegrals is applied to calculate the temporal spectra and dispersion

Investigating Alfvénic Turbulence in Fast and Slow Solar Wind Streams

open access: yesUniverse, 2022
Solar wind turbulence dominated by large-amplitude Alfvénic fluctuations, mainly propagating away from the Sun, is ubiquitous in high-speed solar wind streams. Recent observations performed in the inner heliosphere (from 1 AU down to tens of solar radii)

Hybrid Simulation and Quasi-linear Theory of Bi-Kappa Proton Instabilities

open access: yesThe Astrophysical Journal, 2023
The quasi-steady states of collisionless plasmas in space (e.g., in the solar wind and planetary environments) are governed by the interactions of charged particles with wave fluctuations.

How did the solar wind structure change around the solar maximum? From interplanetary scintillation observation [PDF]

open access: yesAnnales Geophysicae, 2003
Observations from the second Ulysses fast latitude scan show that the global structure of solar wind near solar maximum is much more complex than at solar minimum.

On the Variation of Intermittency of Fast and Slow Solar Wind With Radial Distance, Heliospheric Latitude, and Solar Cycle

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Intermittency, an important property of astrophysical plasma turbulence, is studied extensively during last decades from in-situ measurements of the solar wind plasma and magnetic field in the ecliptic plane and at higher latitudes, and heliocentric ...
