Rational Approximation Formula for Chandrasekhar's H-function for Isotropic Scattering
Rational Approximation Formula Chandrasekhar's H-function
2011/1/10
We first establish a simple procedure to obtain with 11-figure accuracy the values of Chandrasekhar's H-function for isotropic scattering using a closed-form integral representation and the Gauss-Lege...
Propagation of the burst of radiation in expanding and recombining Universe: Thomson scattering
radiation expanding recombining Universe
2011/1/10
Within the framework of a flat cosmological model a propagation of an instantaneous burst of nonpolarized isotropic radiation is considered from the moment of its beginning at some initial redshift z0...
Scattering of helioseismic waves by a sunspot: wavefront healing and folding
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We observe and characterize the scattering of acoustic wave packets by a sunspot, in a regime where the wavelength is comparable to the size of the sunspot. Spatial maps of wave traveltimes and amplit...
STUDY OF COMPTON BROADENING DUE TO ELECTRON-PHOTON SCATTERING
Stars: atmospheres Radiative transfer Scattering
2010/10/29
We have investigated the effects of Compton broadening due to
electron-photon scattering in hot stellar atmospheres. A purely electron-photon
scattering media is assumed to have plane parallel geome...
Last scattering, relic gravitons and the circular polarization of the CMB
relic gravitons circular polarization
2010/3/19
The tensor contribution to the $V$-mode polarization induced by a magnetized plasma at last scattering vanishes exactly. Conversely a polarized background of relic gravitons cannot generate a $V$-mode...

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...
