We present results from a two-fluid model of the solar wind which includes the thermal gas and a non-thermal particle population. Low-energy solar cosmic rays (10 to 100 keV) can help accelerate the wind by transferring some of their momentum to comoving magnetic irregularities. We find ...
particle accelerationand transport, magnetic reconnection, and turbulence and waves. Proof of the existence of the solar wind was one of the first great triumphs of the space age, and much has been learned about the physical nature of the wind and related processes in intervening years. ...
It is discussed how the temporal evolution of the injection and acceleration process can result in solar energetic particle spectra that differ substantially from the prediction of standard steady state diffusive shock acceleration models.关键词: Solar wind Solar energetic particles Protons Solar corona ...

The most stringent test of theoretical models of the first-order Fermi mechanism at collisionless astrophysical shocks is a comparison of the theoretical predictions with observational data on particle populations. Such comparisons have yielded good agre

In this review, we discuss critically recent research on the acceleration of the solar wind, giving emphasis to high-speed solar wind streams emanating from solar coronal holes. We first explain why thermally driven wind models constrained by solar and interplanetary observations encounter substantial ...

"While early models of the solar wind relied primarily on thermal energy to accelerate the material, by the 1960s it was clear that thermal acceleration alone cannot account for the high speed of solar wind. An additional unknown acceleration mechanism is required and likely relates to magnetic ...
