X-ray properties of early-type stars in the Tarantula Nebula from T-ReX
Paul A Crowther, Patrick S Broos, Leisa K Townsley +3
We reassess the historical relation for early-type stars from a comparison between T-ReX, the Chandra ACIS X-ray survey of the Tarantula Nebula in the LMC, and cont…
Melnick 33Na: a very massive colliding wind binary system in 30 Doradus
Joachim M. Bestenlehner, Paul A. Crowther, Patrick S. Broos +2
We present spectroscopic analysis of the luminous X-ray source Melnick 33Na (Mk 33Na, HSH95 16) in the LMC 30 Doradus region (Tarantula Nebula), utilising new time-series VLT/UVES…
Competitive X-ray and Optical Cooling in the Collisionless Shocks of WR 140
A. M. T. Pollock, M. F. Corcoran, I. R. Stevens +9
WR 140 is a long-period, highly eccentric Wolf-Rayet star binary system with exceptionally well-determined orbital and stellar parameters. Bright, variable X-ray emission is genera…
X-ray spectra, light-curves and SEDs of blazars frequently observed by Swift
P. Giommi, M. Perri, M. Capalbi +19
Blazars research is one of the hot topics of contemporary extra-galactic astrophysics. That is because these sources are the most abundant type of extra-galactic gamma-ray sources…
The Colliding Winds of WR 25 in High Resolution X-rays
Pragati Pradhan, David P. Huenemoerder, Richard Ignace +2
WR 25 is a colliding-wind binary star system comprised of a very massive O2.5If*/WN6 primary and an O-star secondary in a 208-day period eccentric orbit. These hot stars have stron…
Conditions in the WR 140 wind-collision region revealed by the 1.083-micron He I line profile
Peredur M. Williams, Watson P. Varricatt, André-Nicolas Chené +10
We present spectroscopy of the P~Cygni profile of the 1.083-micron He I line in the WC7 + O5 colliding-wind binary (CWB) WR 140 (HD 193793), observed in 2008, before its periastron…
