Abstract:
Type Ic supernovae represent the explosions of the most stripped
massive stars, but their progenitors and explosion mechanisms remain
unclear. Larger samples of observed supernovae can help characterize
the population of these transients. We present an analysis of 44
spectroscopically normal Type Ic supernovae, with focus on the light
curves. The photometric data were obtained over 7 years with the
Palomar Transient Factory (PTF) and its continuation, the intermediate
Palomar TransientFactory (iPTF). This is the first homogeneous and
large sample of SNe Ic from an untargeted survey, and we aim to
estimate explosion parameters for the sample.
Description:
SN discovery and early photometric observations were performed with
the 48-inch Samuel Oschin Telescope at Palomar Observatory (P48),
equipped with the 96 Mpx mosaic camera CFH12K (Rahmer et al., 2008,
Proc. SPIE, 7014,), a Mould r-band filter (Ofek et al.
2012PASP..124...62O 2012PASP..124...62O) and a g-band filter. For 34 SNe in our sample,
further follow-up was performed with the automated Palomar 60-inch
telescope (P60, Cenko et al., 2006PASP..118.1396C 2006PASP..118.1396C), often in Bgri
bands.
