Scattering polarization due to light source anisotropy
R Ignace, M Al-Malki, J Simmons +3
We consider the polarization arising from scattering in an envelope illuminated by a central anisotropic source. Spherical harmonics are used to describe both the light source anis…
Fast Spectral Fitting of Hard X-Ray Bremsstrahlung from Truncated Power-Law Electron Spectra
J. C. Brown, J. Kasparova, A. M. Massone +1
Hard X-Ray bremsstrahlung continuum spectra, such as from solar flares, are commonly described in terms of power-law fits, either to the photon spectra themselves or to the electro…
X-ray Emission from Magnetically Torqued Disks of Oe/Be Stars
Q. Li, J. P. Cassinelli, J. C. Brown +2
We focus attention on the Oe/Be stars to test the concept that the disks of these stars form by magnetic channeling of wind material toward the equator. Calculations are made of th…
RHESSI Results -- Time For a Rethink?
J. C. Brown, E. P. Kontar, A. M. Veronig
Hard X-rays and gamma-rays are the most direct signatures of energetic electrons and ions in the sun's atmosphere which is optically thin at these energies and their radiation invo…
The Effect of Rotational Gravity Darkening on Magnetically Torqued Be Star Disks
J. C. Brown, D. Telfer, Q. Li +3
In the magnetically torqued disk (MTD) model for hot star disks, as proposed and formulated by \citet{cassi02}, stellar wind mass loss was taken to be uniform over the stellar surf…
Optically Thick Clumps - Not the Solution to the Wolf-Rayet Wind Momentum Problem?
J C Brown, J P Cassinelli, Q Li +2
The hot star wind momentum problem η= mdot*vinfty/(L/c) >> 1 is revisited, and it is shown that the conventional belief, that it can be solved by a combination of clumping of the w…
