Recent results of our HST/WFC3 survey of Wolf-Rayet stars in M101 are summarised based on the detection efficiency of narrow-band optical imaging compared to broad-band methods. Weshow that on average of 42% WR stars, increasing to ~85% in central regions, are only detected in the narrow-band imaging. Hence, the non-detection of a WR star at the location of ~10 Type Ib/c SNe in broad-band imaging is no longer strong evidence for a non-WR progenitor channel.", "revisions": [ { "version": "v1", "updated": "2012-04-16T13:49:09.000Z" } ], "analyses": { "keywords": [ "wolf-rayet stars", "type ib/c core-collapse supernovae", "wr star", "non-wr progenitor channel", "type ib/c sne" ], "tags": [ "journal article" ], "publication": { "doi": "10.1017/S1743921312012781", "journal": "Death of Massive Stars: Supernovae and Gamma-Ray Bursts", "year": 2012, "month": "Sep", "volume": 279, "pages": 118 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1110969, "adsabs": "2012IAUS..279..118B" } } }
