The evolution of the solar wind. [PDF]

Living Rev Sol Phys, 2021
How has the solar wind evolved to reach what it is today? In this review, I discuss the long-term evolution of the solar wind, including the evolution of observed properties that are intimately linked to the solar wind: rotation, magnetism and activity.

Directly comparing coronal and solar wind elemental fractionation [PDF]

A&A 640, A28 (2020), 2020
As the solar wind propagates through the heliosphere, dynamical processes irreversibly erase the signatures of the near-Sun heating and acceleration processes. The elemental fractionation of the solar wind should not change during transit however, making it an ideal tracer of these processes.

Quantifying the latitudinal representivity of in situ solar wind observations [PDF]

Journal of Space Weather and Space Climate, 2020
Advanced space-weather forecasting relies on the ability to accurately predict near-Earth solar wind conditions. For this purpose, physics-based, global numerical models of the solar wind are initialized with photospheric magnetic field and coronagraph ...

On slow solar wind with high Alfvénicity: from composition and microphysics to spectral properties [PDF]

Monthly notices of the Royal Astronomical Society, 2018
Alfv\'enic fluctuations are very common features in the solar wind and are found especially within the main portion of fast wind streams while the slow wind usually is less Alfv\'enic and more variable. In general, fast and slow wind show many differences which span from the large scale structure to small scale phenomena including also a different ...

Neutral Solar Wind Generated by Lunar Exospheric Dust at the Terminator [PDF]

, 2008
We calculate the flux of neutral solar wind observed on the lunar surface at the terminator due to solar wind protons penetrating exospheric dust grains with (1) radii greater than 0.1 microns and (2) radii greater than 0.01 microns. For grains with radii larger than 0.1 microns, the ratio of the neutral solar wind flux produced by exospheric dust to ...

The influence of solar wind variability on magnetospheric ULF wave power [PDF]

Annales Geophysicae, 2015
Magnetospheric ultra-low frequency (ULF) oscillations in the Pc 4–5 frequency range play an important role in the dynamics of Earth's radiation belts, both by enhancing the radial diffusion through incoherent interactions and through the coherent ...

Cross Helicity and the Helium Abundance as an In Situ Metric of Solar Wind Acceleration [PDF]

The Astrophysical Journal Letters
The two-state solar wind paradigm is based on observations showing that slow and fast solar wind have distinct properties like helium abundances, kinetic signatures, elemental composition, and charge-state ratios. Nominally, the fast wind originates from

Reconstruction of Helio-latitudinal Structure of the Solar Wind Proton Speed and Density [PDF]

, 2015
The modeling of the heliosphere requires continuous three-dimensional solar wind data. The in-situ out-of-ecliptic measurements are very rare, so that other methods of solar wind detection are needed.

Magnetic Reconnection as the Driver of the Solar Wind [PDF]

Astrophysical Journal, 2023
We present EUV solar observations showing evidence for omnipresent jetting activity driven by small-scale magnetic reconnection at the base of the solar corona.

Two Level Control Strategy for Independent AC/DC Hybrid Microgrid Based on Integrated Control [PDF]

E3S Web of Conferences, 2021
Aiming at the independent AC/DC microgrid, a simple and effective multi time scale control strategy is proposed by adopting the combination of day ahead scheduling and real-time control.
