Rapid density fluctuations in the solar wind

Electron density fluctuations (up to 2.5 Hz) in the solar wind have been studied, using the EFW experiment on the Cluster spacecraft, which measures density through measurements of the biased probe potentials relative to the spacecraft. The density fluctuation spectra obtained from the EFW probe potential variations are compared to earlier, OGO 5, measurements of ion density fluctuations and IS...

Solar wind periodicity in energetic electrons at Saturn

[1] Fluxes of energetic electrons (110–365 keV) have been subjected to a long-term Lomb periodogram analysis from the middle of 2004 to the middle of 2009. Fluxes within 20 RS and outside the magnetopause were excluded, so only fluxes within the magnetosphere were included in the analysis. The periodicity ‘‘box’’ was expanded from 5 hours to 50 days. In addition to the familiar rotational perio...

Neutral interstellar gas atoms reducing the solar wind Mach number and fractionally neutralizing the solar wind

Many stars are known to drive stellar winds of the solar wind type. Thus when moving through the ambient interstellar medium these stars not simply ionize this medium but also interact as moving stellar wind systems. Only neutral interstellar gas components can directly enter the inner stellar wind region and there undergo charge exchange reactions with the supersonic stellar wind protons. Ther...

The 13.5-day periodicity in the Sun, solar wind, and geomagnetic activity: The last three solar cycles

We make a detailed analysis of the 13.5-day periodicity of the solar chromosphere, the nearEarth solar wind, interplanetary magnetic field and geomagnetic activity during the last three solar cycles. The 13.5-day periodicity is a real quasi-periodicity whose amplitude varies sizably with time, attaining occasionally values larger than, for example, the amplitude of the 27-day periodicity. In ca...

Large-scale velocity fluctuations in polar solar wind

The 3-D structure of the solar wind varies dramatically along the Sun’s activity cycle. In the present paper we focus on some properties of the polar solar wind. This is a fast, teneous, and steady flow (as compared to low-latitude conditions) that fills the high-latitude heliosphere at low solar activity. The polar wind has been extensively investigated by Ulysses, the first spacecraft to perf...
