Ultraviolet Coronagraph Spectroscopy: A Key Capability for Understanding the Physics of Solar Wind Acceleration
Ultraviolet Coronagraph Spectroscopy Physics of Solar Wind Acceleration
2010/11/15
Understanding the physical processes responsible for accelerating the solar wind requires detailed measurements of the collisionless plasma in the extended solar corona. Some key clues about these pro...
Solar Wind Drag and the Kinematics of Interplanetary Coronal Mass Ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the solar corona, which propagate through interplanetary space at velocities of $\sim$100--2500~km~s$^{-1}$.
Anisotropic unstable ion distribution functions downstream of the solar wind termination shock
ion plasma state solar wind
2009/5/27
In this paper we demonstrate that solar wind ions, passing over the quasiperpendicular portion of the solar wind MHD termination shock, unavoidably develop strongly pronounced pitchangle anisotropies....
Self-initialised Fermi-1 acceleration by pitch-angle re-scattering of solar wind ions reflected from the parallel termination shock
anomalous cosmic ray process governing pick-up ions solar wind ions
2009/5/27
In a recent kinetic calculation a rather high amount of reflected ions was shown to occur at the solar wind termination shock under a parallel magnetic field orientation. The fate of these reflected i...
May 17, 2007，Helium may act as a "throttle" for the solar wind, setting its minimum speed, according to new results from an MIT-led team using NASA’s Wind spacecraft.
