Properties of Hot, Massive Stars: The Impact of FUSE
Paul A. Crowther
The impact of FUSE upon the fundamental parameters of OB stars and Wolf-Rayet stars is reviewed. The stellar wind signatures available in the far-UV provide us with important addit…
Stellar Parameters of Wolf-Rayet Stars from Far-UV to Mid-IR Observations
Paul A Crowther
Recent results for Galactic and Magellanic Cloud Wolf-Rayet stars are summarised based on line blanketed, clumped model atmospheres together with UV, optical and IR spectroscopy. T…
Far-UV FUSE spectroscopy of the OVI resonance doublet in Sand2 (WO)
Paul A. Crowther, A. W. Fullerton, D. J. Hillier +10
We present Far-Ultraviolet Spectroscopic Explorer (FUSE) spectroscopy of Sand 2, a LMC WO-type Wolf-Rayet star, revealing the OVI resonance P Cygni doublet at 1032-38A. These data…
Wind properties of Wolf-Rayet stars at low metallicity: Sk41 (SMC)
Paul A. Crowther
The stellar properties of Sk41 (AB4, WN5h), the only known single Wolf-Rayet star in the SMC, are derived from ultraviolet (IUE), optical (AAT) and near-IR (NTT) spectroscopy. Cont…
Wolf-Rayet nebulae as tracers of stellar ionizing fluxes: I. M1-67
P. A. Crowther, A. Pasquali, O. De Marco +3
We use WR124 (WN8h) and its associated nebula M1-67, to test theoretical non-LTE models for Wolf-Rayet (WR) stars. Lyman continuum ionizing flux distributions derived from a stella…
