Atomic data for neutron-capture elements II. Photoionization and recombination properties of low-charge krypton ions
atomic data - atomic processes - HII regions - nucleosynthesis, abundances - planetary nebulae: general - stars:evolution
2011/10/12
We present multi-configuration Breit-Pauli distorted-wave photoionization (PI) cross sections and radiative recombination (RR) and dielectronic recombination (DR) rate coefficients for the first six k...
The Effect of Magnetic Turbulence Energy Spectra and Pickup Ions on the Heating of the Solar Wind
Pickup ions, Solar wind heating, MHD turbulence, Wave-particle interaction
2011/9/9
In recent years, a phenomenological solar wind heating model based on a turbulent energy cascade prescribed by the Kolmogorov theory has produced reasonably good agreement with observations on proton ...
Magnetic field amplification and electron acceleration to near-energy equipartition with ions by a mildly relativistic quasi-parallel plasma protoshock
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
The prompt emissions of gamma-ray bursts are seeded by radiating ultrarelativistic electrons. Internal shocks propagating through a jet launched by a stellar implosion, are expected to amplify the mag...

Expansion velocities from different ions of planetary nebulae with [wc]-type central stars。
Necessary conditions for the generation of acoustic solitons in magnetospheric and space plasmas with hot ions
acoustic solitons space plasmas magnetospheric
2009/5/27
Necessary conditions are discussed for the possible generation of large solitary acoustic modes in plasmas with one or more ion species which are hotter than some or all of the electron species. The a...
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...
ESTIMATION OF ELECTRON-IMPACT LINE WIDTHS FOR SINGLY-, DOUBLY- AND TRIPLY-CHARGED VANADIUM IONS
ELECTRON-IMPACT LINE DOUBLY- SINGLY- TRIPLY-CHARGED VANADIUM IONS
2009/3/26
In this paper we present the electron-impact widths for 28 transitions
of singly-, doubly-, and triply- ionized vanadium estimated by using the
modified semiempirical method. The electron-impact wid...
