Abstract:
We investigate two stripped-envelope supernovae (SNe) discovered in
the nearby galaxy NGC 5806 by the (i)PTF. We classify PTF12os as a
Type IIb SN based on our spectral sequence; iPTF13bvn has previously
been classified as Type Ib. Our main objective is to constrain the
explosion parameters of iPTF12os and iPTF13bvn, and to put constraints
on the SN progenitors, using our comprehensive photometric and
spectroscopic datasets.
Description:
Photometric and spectroscopic datasets of PTF12os and iPTF13bvn. Our
dataset on PTF12os spans from approximately 8.5 days to 215 days past
the SN explosion and it contains optical photometry and spectra. Our
data on iPTF13bvn spans from approximately 0.6 to 380 days. The
dataset on iPTF13bvn contains optical photometry and optical/infrared
spectroscopy.
