Nonlinear waves and solitons propagating perpendicular to the magnetic field in bi-ion plasma with finite plasma pressure
Nonlinear waves solitons propagating perpendicular magnetic field bi-ion plasma plasma pressure
2009/11/12
We investigate the nature of nonlinear waves propagating transverse to the magnetic field in a bi-ion plasma including plasma pressure. By using the conservation laws derived from the multi-ion fluid ...
In a recent paper de Paor put forward a new theory of the Earth's magnetic field that depended on the Hall effect as an energy transfer mechanism. The purpose of this paper is to demonstrate that the ...
Clarification of the Hall effect as an energy transfer mechanism in a theory of the Earth’s magnetic field and sunspots
Hall effect energy transfer mechanism Earth’s magnetic field and sunspots
2009/11/12
Clarification is offered of the energy transfer role played by the Hall effect in a recent paper: de Paor, A., A theory of the Earth's magnetic field and of sunspots, based on a self-excited dynamo in...
Magnetic field turbulence,electron heating,magnetic holes,proton cyclotron waves,and the onsets of bipolar pulse (electron hole) events:a possible unifying scenario
Magnetic field turbulence electron heating magnetic holes proton cyclotron waves
2009/11/11
Two electron heating events have been identified on 20 May 1996 when Polar was in the polar cap/polar cusp boundary layer. The electron heating events were located within magnetic holes/cavities/bubbl...
Multifractal structure of the large-scale heliospheric magnetic field strength fluctuations near 85AU
Multifractal structure magnetic field strength fluctuations 85AU
2009/11/11
During 2002, the Voyager 1 spacecraft was in the heliosphere between 83.4 and 85.9AU (1AU is the mean distance from the Sun to Earth) at 34° N heliographic latitude. The magnetic field strength profil...
A probabilistic approach to heterogeneity in space plasmas:the case of magnetic field intensity in solar wind
probabilistic approach heterogeneity space plasmas magnetic field intensity
2009/10/30
Since the early 90s it was shown that Probability Distribution Functions (PDFs) of small scale differences (fluctuations) of several quantities in space plasmas display significant departures from Gau...
Advection/diffusion of large scale magnetic field in accretion disks
Advection diffusion large scale magnetic field accretion disks
2009/10/30
Activity of the nuclei of galaxies and stellar mass systems involving disk accretion to black holes is thought to be due to (1) a small-scale turbulent magnetic field in the disk (due to the magneto-r...
Spin polarization phenomena in dense neutron matter at a strong magnetic field
Spin polarization phenomena dense neutron matter magnetic field
2011/1/6
Spin polarized states in neutron matter at strong magnetic fields up to 1018 G are considered
in the model with the Skyrme effective interaction. Analyzing the self-consistent equations at zero tempe...
SGRs and AXPs：Evidence for Delayed Amplification of Magnetic Field after Neutron Star Formation?
Anomalous X-ray Pulsars soft gamma-ray repeaters supernova remnants
2009/9/4
We present new analysis of the birth rate of AXPs and SGRS and their associated SNRs. Using Kolmogorov-Smirnov statistics together with parametric fits based on a robust estimator, we find a birth rat...
A Method for Judging Decay or Growth of the Magnetic Field of Pulsar
Pulsar—decay or growth of magnetic field—method of judgement
2010/9/15
This paper provides a method for judging growth or decay of the magnetic field of pulsar by using pulse period P, or frequency ν, and its first and second derivatives P˙, P¨ or ν˙, ν¨. The author uses...
Neutrino energy loss by electron capture in magnetic field at the crusts of neutron stars
strong magnetic field neutrino energy loss neutron star
2009/7/31
Based on the p-f shell model, the effect of strong magnetic field on neutrino energy loss rates by electron capture is investigated. The calculations show that the magnetic field has only a slight eff...
Magnetic field in the solar lower atmosphere can be measured by the use of the Zeeman and Hanle effects. In contrast, the coronal magnetic field well above the solar surface, which directly controls v...
