Fractionation of the Solar Wind [PDF]
The composition of the solar wind (SW) is not a true sample of the solar composition, but it is fractionated with respect to the solar photosphere. This fractionation follows the well-known first ionization potential (FIP) pattern: When plotting the SW abundances with respect to the solar abundances as a function of FIP, a step function is obtained ...

Multifractality and intermittency in the solar wind [PDF]
Abstract. Within the complex dynamics of the solar wind's fluctuating plasma parameters, there is a detectable, hidden order described by a chaotic strange attractor which has a multifractal structure. The multifractal spectrum has been investigated using Voyager (magnetic field) data in the outer heliosphere and using Helios (plasma) data in the inner

The Relationship Between Solar Wind Dynamic Pressure Pulses and Solar Wind Turbulence
Solar wind dynamic pressure pulses (DPPs) are small-scale plasma structures with abrupt and large-amplitude plasma dynamic pressure changes on timescales of seconds to several minutes.

The Pickup Ion-mediated Solar Wind
The New Horizons Solar Wind Around Pluto (NH SWAP) instrument has provided the first direct observations of interstellar and He pickup ions (PUIs) at distances between ∼11.26 and 38 au in the solar wind.

AbstractThis review discusses winds from stars with hot outer atmospheres, stars with coronae similar to the sun. It illustrates how solar observations can be used to test a theoretical model for solar-stellar winds, and thereby provide some insights concerning applications to studying winds from stars other than the sun.

The near-Sun streamer belt solar wind: turbulence and solar wind acceleration [PDF]
The fourth orbit of Parker Solar Probe (PSP) reached heliocentric distances down to 27.9R⊙, allowing solar wind turbulence and acceleration mechanisms to be studied in situ closer to the Sun than previously possible. The turbulence properties were found to be significantly different in the inbound and outbound portions of PSP’s fourth solar encounter ...

Are periodic solar wind number density structures formed in the solar corona? [PDF]
[1] We present an analysis of the alpha to proton solar wind abundance ratio (AHe) during a period characterized by significant large size scale density fluctuations, focusing on an event in which the proton and alpha enhancements are anti-correlated. In
