dc.description.abstractWe present an extensive set of photometric and spectroscopic data for SN 2009jf, a nearby Type Ib supernova, spanning from 20 days before B-band maximum to one year after maximum. We show that SN 2009jf is a slowly evolving and energetic stripped-envelope SN and is likely from a massive progenitor (25-30 solar masses). The large progenitor’s mass allows us to explain the complete hydrogen plus helium strip- ping without invoking the presence of a binary companion. The supernova occurred close to a young cluster, in a crowded environment with ongoing star-formation. The specroscopic similarity with the He-poor Type Ic SN 2007gr suggests a common pro- genitor for some supernovae Ib and Ic. The nebular spectra of SN 2009jf are consistent with an asymmetric explosion, with an off-center dense core. We also find evidence that He-rich Ib supernovae have a rise time longer than other stripped-envelope su- pernovae, however confirmation of this result and further observations are needed.en
