Slow Solar Wind Connection Science during Solar Orbiter’s First Close Perihelion Passage

The Astrophysical Journal Supplement Series, 2023
The Slow Solar Wind Connection Solar Orbiter Observing Plan (Slow Wind SOOP) was developed to utilize the extensive suite of remote-sensing and in situ instruments on board the ESA/NASA Solar Orbiter mission to answer significant outstanding questions ...

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

Annales 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.

EISCAT measurements of the solar wind [PDF]

Annales 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

The 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]

Radio 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

Observational Evidence of S-web Source of the Slow Solar Wind

The Astrophysical Journal, 2023
From 2022 March 18 to 21, NOAA Active Region (AR) 12967 was tracked simultaneously by Solar Orbiter at 0.35 au and Hinode/EIS at Earth. During this period, strong blueshifted plasma upflows were observed along a thin, dark corridor of open magnetic field

Parker Solar Probe Observations of High Plasma β Solar Wind from the Streamer Belt

The Astrophysical Journal Supplement Series, 2023
In general, slow solar wind from the streamer belt forms a high plasma β equatorial plasma sheet around the heliospheric current sheet (HCS) crossing, namely, the heliospheric plasma sheet (HPS).

Investigating Alfvénic Turbulence in Fast and Slow Solar Wind Streams

Universe, 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)
