Gamma-ray variability from wind clumping in HMXBs with jets
S. P. Owocki, G. E. Romero, R. H. D. Townsend +1
In the subclass of high-mass X-ray binaries known as "microquasars", relativistic hadrons in the jets launched by the compact object can interact with cold protons from the star's…
A Rigid-Field Hydrodynamics approach to modeling the magnetospheres of massive stars
R. H. D. Townsend, S. P. Owocki, A. ud-Doula
We introduce a new Rigid-Field Hydrodynamics approach to modeling the magnetospheres of massive stars in the limit of very-strong magnetic fields. Treating the field lines as effec…
Magnetic fields and UV-line variability in Cephei
R. S. Schnerr, H. F. Henrichs, S. P. Owocki +2
We present results of numerical simulations of wind variability in the magnetic B1 IVe star Cephei. 2D-MHD simulations are used to determine the structure of the wind. From the…
Kappa-mechanism excitation of retrograde mixed modes in rotating B-type stars
R. H. D. Townsend
I examine the stability of retrograde mixed modes in rotating B-type stars. These modes can be regarded as a hybrid between the Rossby modes that arise from conservation of vortici…
On the evidence for discs around Blue Straggler stars
John M. Porter, R. H. D. Townsend
Recent observations of blue stragglers by De Marco et al. (2004) have revealed continuum deficits on the blue side of the Balmer discontinuity, leading these authors to infer the p…
The Rigidly Rotating Magnetosphere of Sigma Ori E
R. H. D. Townsend, S. P. Owocki, D. Groote
We attempt to characterize the observed variability of the magnetic helium-strong star sigma Ori E in terms of a recently developed rigidly rotating magnetosphere model. This model…
