The solar wind is a magnetized plasma and as such exhibits collective plasma behavior
associated with its characteristic spatial and temporal scales. The characteristic length …

The present paper comprises a review of kinetic instabilities that may be operative in the
solar wind, and how they influence the dynamics thereof. The review is limited to collective …

Switchbacks (rotations of the magnetic field) are observed on the Parker Solar Probe. Their
evolution, content, and plasma effects are studied in this paper. The solar wind does not …

Hybrid-kinetic numerical simulations of firehose and mirror instabilities in a collisionless
plasma are performed in which pressure anisotropy is driven as the magnetic field is …

We report an analysis of the proton temperature anisotropy evolution from 0.3 to 2.5 AU
based on the Helios and Ulysses observations. With increasing distance the fast wind data …

Major geomagnetic storms are caused by unusually intense solar wind southward magnetic
fields that impinge upon the Earth's magnetosphere (Dungey, 1961). How can we predict the …

Kinetic microinstabilities in the solar wind arise when the plasma deviates too far from
thermal equilibrium. Previously published work has provided strong evidence that the …

One of the discoveries of the Parker Solar Probe during its first encounters with the Sun is
ubiquitous presence of relatively small-scale structures standing out as sudden deflections …

We discuss selected ion kinetic processes relevant in the context of the expanding solar
wind. We focus on the role of wave-wave and wave-particle interactions, plasma instabilities …

In this paper we give firstly a broad review of the space plasma turbulence around the ion
characteristic space and temporal scales within two natural laboratories, the solar wind and …
