Abstract
dc.description.abstract
We present an extensive set of photometric and spectroscopic data for SN 2009jf, a nearby
Type Ib supernova (SN), spanning from∼20 d before B-band maximum to 1 yr after maximum.
We show that SN 2009jf is a slowly evolving and energetic stripped-envelope SN and is likely
from a massive progenitor (25–30M ). The large progenitor’s mass allows us to explain the
complete hydrogen plus helium stripping without invoking the presence of a binary companion.
The SN occurred close to a young cluster, in a crowded environment with ongoing star
formation. The spectroscopic similarity with the He-poor Type Ic SN 2007gr suggests a
common progenitor for some SNe Ib and Ic. The nebular spectra of SN 2009jf are consistent
with an asymmetric explosion, with an off-centre dense core. We also find evidence that Herich
Ib SNe have a rise time longer than other stripped-envelope SNe, however confirmation
of this result and further observations are needed.
