On the association between core-collapse supernovae and HII regions
Paul A. Crowther
Previous studies of the location of core-collapse supernovae (ccSNe) in their host galaxies have variously claimed an association with HII regions; no association; or an associatio…
IC4663: the first unambiguous [WN] Wolf-Rayet central star of a planetary nebula
Brent Miszalski, Paul A. Crowther, Orsola De Marco +4
Several [WC]-type central stars of planetary nebulae (PNe) are known to mimic the spectroscopic appearance of massive carbon-rich or WC-type Wolf-Rayet stars. In stark contrast, no…
Very Massive Stars and the Eddington Limit
Paul A. Crowther, R. Hirschi, Nolan R. Walborn +1
We use contemporary evolutionary models for Very Massive Stars (VMS) to assess whether the Eddington limit constrains the upper stellar mass limit. We also consider the interplay b…
Environments of massive stars and the upper mass limit
Paul A. Crowther
The locations of massive stars (> 8 Msun) within their host galaxies is reviewed. These range from distributed OB associations to dense star clusters within giant HII regions. A co…
IC 4663: The first unambiguous [WN] Wolf-Rayet central star of a planetary nebula
B. Miszalski, P. A. Crowther, O. De Marco +4
We report on the serendipitous discovery of the first central star of a planetary nebula (PN) that mimics the helium- and nitrogen-rich WN sequence of massive Wolf-Rayet (WR) stars…
