Interplanetary plasma irregularities and ion acoustic turbulence

Physics Reports, 1990
Abstract In this paper we discuss an effect of the ion acoustic turbulence on the inhomogeneous stucture of complementary ionized interplanetary and interstellar plasmas. These media are practically collisionless and their irregularities are of scales (along the magnetic field lines) much smaller than the mean free path of the electrons. However, the

Plasma wave turbulence associated with an interplanetary shock

Journal of Geophysical Research, 1979
In this paper we give a brief summary of the interplanetary shocks detected and analyzed to date from the Helios 1 and 2 spacecraft and present a detailed analysis of the plasma wave turbulence associated with one particular shock, on March 30, 1976. This event was selected because a very clearly defined burst of plasma wave turbulence occurs at the ...

Turbulence and Scintillations in the Interplanetary Plasma

Annual Review of Astronomy and Astrophysics, 1973
The properties of the broadband fluctuations of the interplanetary plasma are discussed, taking into account observations in the vicinity of 1 AU heliocentric radius on space probes. Aspects of interplanetary scintillations and angular broadening as a probe of the solar wind are considered, giving attention to the 'thin-screen' approximation, a three ...

Nonlocal plasma turbulence associated with interplanetary shocks

Journal of Geophysical Research, 1982
The plasma wave instrument on ISEE 3 has detected regions of plasma turbulence that extend several tenths of an astronomical unit upstream or downstream of inteplanetary shocks. The plasma waves fall into four categories. Highly impulsive 1‐ 10‐kHz electric field bursts were found hours upstream of quasi‐parallel interplanetary shocks.

Fully Developed Anisotropic Hydromagnetic Turbulence in Interplanetary Space

Physical Review Letters, 1980
The solar-wind magnetohydrodynamic turbulence is observed to be mainly made of Alfv\'enic fluctuations propagating away from the sun. It is shown that such an asymmetric state is a general consequence of the evolution of developed magnetohydrodynamic turbulence, which, starting from an initial asymmetry between modes with cross helicity + 1 and - 1 ...

Observations of Turbulence near Interplanetary Travelling Shocks

AIP Conference Proceedings, 2005
The observations on magnetic field fluctuations and suprathermal ion spectra near the shocks driven by the coronal mass ejections during the time periods of the Bastille Day 2000 event and the Halloween 2003 events are summarized.

Turbulence properties associated with interplanetary shock waves

AIP Conference Proceedings, 2012
We calculate the power spectral densities of magnetic field fluctuations associated with interplanetary shock waves, utilizing in-situ magnetic field measurements from spacecraft ACE and Wind at 1AU. We derive related quantities both upstream and downstream of a shock as a function of time/distance away from the shock passage.

Magnetic field strength distribution in interplanetary turbulence

Journal of Geophysical Research: Space Physics, 2000
The distribution of magnetic field magnitudes is derived for the special case of a constant mean field and uncorrelated components having Gaussian distributions. Of the three cases considered (isotropic, transverse, and axisymmetric) the latter most closely resembles a lognormal distribution when the parallel variance is less than the perpendicular ...

Scintillation, density and turbulence in the interplanetary medium

Planetary and Space Science, 1990
Abstract An attempt is made to reconcile the different power laws obtained when relating, on the one hand, interplanetary scintillation (IPS) to solar-wind density and, on the other, density turbulence to density. A numerical experiment was performed using a 2-D magnetohydrodynamical (MHD) model to simulate the solar wind in the ecliptic plane and ...

The magnetic field turbulence near interplanetary shock fronts

Advances in Space Research, 1984
The power spectra (frequency range 10−3 to 10−2 Hz) of the magnetic field fluctuations near interplanetary shock fronts (IPS) are analysed using Venera 13 and Venera 14 data. Ten events in teh period from November, 1981 to February, 1982 typical for IPS passings are evaluated. The event on February 2, 1982 is considered in detail.
