Westerlund 1 as a Template for Massive Star Evolution
Ignacio Negueruela, J. Simon Clark, Paul A. Crowther +1
With a dynamical mass M_dyn ~ 1.3x10e5 M_sun and a lower limit M_cl>5x10e4 M_sun from star counts, Westerlund 1 is the most massive young open cluster known in the Galaxy and thus…
A survey of the Wolf-Rayet population of the barred, spiral galaxy NGC 1313
L. J. Hadfield, P. A. Crowther
We present a VLT/FORS1 survey of Wolf-Rayet (WR) stars in the spiral galaxy NGC 1313. In total, 94 WR candidate sources have been identified from narrow-band imaging. Of these, 82…
On the optical counterpart of NGC300 X-1 and the global Wolf-Rayet content of NGC300
Paul A Crowther, S. Carpano, L. J. Hadfield +1
(Conext:) Surveys of Wolf-Rayet (WR) populations in nearby galaxies provide tests of evolutionary models plus Type Ib/c supernova progenitors. This spectroscopic study complements…
Searching for hidden Wolf-Rayet stars in the Galactic Plane - 15 new Wolf-Rayet stars
L. J. Hadfield, S. D. Van Dyk, P. W. Morris +3
We report the discovery of fifteen previously unknown Wolf-Rayet (WR) stars found as part of an infrared broad-band study of candidate WR stars in the Galaxy. We have derived an em…
A census of the Wolf-Rayet content in Westerlund 1 from near-infrared imaging and spectroscopy
Paul A. Crowther, L. J. Hadfield, J. S. Clark +2
New NTT/SOFI imaging and spectroscopy of the Wolf-Rayet population in Westerlund 1 are presented. Narrow-band near-IR imaging together with follow up spectroscopy reveals four new…
How extreme are the Wolf-Rayet clusters in NGC3125?
L J Hadfield, P A Crowther
We reinvestigate the massive stellar content of NGC3125 (Tol3) using VLT/FORS1 imaging & spectroscopy, plus archival VLT/ISAAC, HST/FOC and HST/STIS datasets. Narrow-band imaging c…
