A Spectroscopic Search for the non-nuclear Wolf-Rayet Population of the metal-rich spiral galaxy M83
Lucy Hadfield, Paul Crowther, Hans Schild +1
We present a catalogue of non-nuclear regions containing Wolf-Rayet stars in the metal-rich spiral galaxy M83 (NGC5236). From a total of 283 candidate regions identified using HeII…
Wind clumping and the wind-wind collision zone in the Wolf-Rayet binary gamma Velorum
H. Schild, M. Guedel, R. Mewe +7
We present XMM-Newton observations of gamma^2 Velorum (WR 11, WC8+O7.5III, P = 78.53 d), a nearby Wolf-Ray binary system, at its X-ray high and low states. At high state, emission…
An exceptional population of late-type WC stars in the metal-rich spiral galaxy
Paul Crowther, Lucy Hadfield, Hans Schild +1
We have surveyed the metal-rich spiral galaxy M83 (NGC5236) for its Wolf-Rayet population using VLT-FORS2 narrow-band imaging and follow-up spectroscopy. From a total of 280 candid…
A large Wolf-Rayet population in NGC300 uncovered by VLT-FORS2
H. Schild, P. A. Crowther, J. B. Abbott +1
We have detected 58 Wolf-Rayet candidates in the central region of the nearby spiral galaxy NGC 300, based on deep VLT-FORS2 narrow-band imaging. Our survey is close to complete ex…
High resolution spectroscopy of symbiotic stars. VI. Orbital and stellar parameters for AR Pav
H. Schild, T. Dumm, U. Muerset +3
We present new dynamical parameters of the AR Pav binary system. Ourobservations consist of a series of high resolution optical/NIR spectra from which we derive the radial velocity…
