Depth profiling analysis of solar wind helium collected in diamond-like carbon film from Genesis
solar wind depth profile helium NASA Genesis mission post-ionization
2017/4/10
The distribution of solar-wind ions in Genesis mission collectors, as determined by depth profiling analysis, constrains
the physics of ion-solid interactions involving the solar wind. Thus, they pro...
Magnetosonic Waveguide Model of Solar Wind Flow Tubes
Solar wind MHD waves magnetic flux tubes
2010/9/17
We consider solar wind flow tubes as a magnetosonic waveguide.Assuming a symmetric expansion in edges of slab-modelled waveguide,we study the propagation characteristics of magnetosonic wave in the so...
Geo-effectiveness of Solar Wind Extremes
Geomagnetic storms geomagnetic activity solar wind streams interplanetary magnetic field space weather
2010/9/16
Examples of extreme events of solar wind and their effect on geomagnetic conditions are discussed here. It is found that there are two regimes of high speed solar wind streams with a threshold ofͬ...
Analysis of Ion Charge States in Solar Wind and CMEs
Solar wind and CMEs Fe ion charge states dielectronic recombination
2010/9/16
We discuss needs in dielectronic recombination data motivated by recent work directed at a quantitative understanding of ion charge states of various elements observed in situ in the solar wind and CM...
Small-scale Alfvènic turbulence in the outer heliosphere is mainly determined by a source which is connected with the instability of the initially highly anisotropic velocity distribution of interstel...

Numerical Simulations of Kinetic Alf ´v en Waves to Study Spectral Index in Solar Wind Turbulence and Particle Heating
Kinetic Alfv´ en wave: filamentation solar wind spectral index chaotic structure
2009/5/6
We present numerical simulations of the modified nonlinear
Schr¨odinger equation satisfied by kinetic Alfv´en waves (KAWs) leading
to the formation of magnetic filaments at different times. Th...
The Solar Wind：Our Current Understanding and How We Got Here
Solar wind coronal holes solar corona cyclotron resonance MHD waves
2009/5/6
In the original theory for the solar wind, the electron pressure
gradient was the principal accelerating force. This was soon recognized
to be insufficient to drive the high-speed streams. Subsequen...

Comparisons between two wavelet functions in extracting coherent structures from solar wind time
Wavelet Analysis Coherent Structures Solar Variables Turbulence
2010/7/5
Nowadays, wavelet analysis of turbulent flows have become increasingly popular. However, the study of geometric characteristics from wavelet functions is still poorly explored. In this work we compare...
