Solar Flare X-ray Source Motion as a Response to Electron Spectral Hardening
A. O'Flannagain, P. Gallagher, J. Brown +2
Context: Solar flare hard X-rays (HXRs) are thought to be produced by nonthermal coronal electrons stopping in the chromosphere, or remaining trapped in the corona. The collisional…
X-ray emission from massive stars with magnetic fields
L. M. Oskinova, W. -R. Hamann, J. P. Cassinelli +2
We investigate the connections between the magnetic fields and the X-ray emission from massive stars. Our study shows that the X-ray properties of known strongly magnetic stars are…
Early magnetic B-type stars: X-ray emission and wind properties
L. M. Oskinova, H. Todt, R. Ignace +3
We present a comprehensive study of X-ray emission and wind properties of massive magnetic early B-type stars. Dedicated XMM-Newton observations were obtained for three stars xi1 C…
Thermalisation and hard X-ray bremsstrahlung efficiency of self-interacting solar flare fast electrons
R. K. Galloway, P. Helander, A. L. MacKinnon +1
Most theoretical descriptions of the production of solar flare bremsstrahlung radiation assume the collision of dilute accelerated particles with a cold, dense target plasma, negle…
Polarization Variability Arising from Clumps in the Winds of Wolf-Rayet Stars
Q. Li, J. P. Cassinelli, J. C. Brown +1
The polarimetric and photometric variability of Wolf-Rayet (WR) stars as caused by clumps in the winds, is revisited. In the model which is improved from Li et al. 2000, the radial…
The Conspicuous Absence of X-ray Emission from Carbon-Enriched Wolf-Rayet Stars
L. M. Oskinova, R. Ignace, W. -R. Hamann +2
The carbon-rich WC5 star WR 114 was not detected during a 15.9 ksec XMM-Newton observation, implying an upper limit to the X-ray luminosity of Lx < 2.5*10^{30} erg/s and to the X-r…
