Abstract:
We present detailed optical photometry for 25 Type Ibc supernovae
(SNe Ibc) within d∼150Mpc obtained with the robotic Palomar 60 inch
telescope in 2004-2007. This study represents the first uniform,
systematic, and statistical sample of multi-band SNe Ibc light curves
available to date. We correct the light curves for host galaxy
extinction using a new technique based on the photometric color
evolution, namely, we show that the (V-R) color of
extinction-corrected SNe Ibc at Δt∼10days after V-band maximum
is tightly distributed, <(V-R)V10≥0.26±0.06mag. Using this
technique, we find that SNe Ibc typically suffer from significant host
galaxy extinction, <E(B-V)≳0.4mag. A comparison of the
extinction-corrected light curves for helium-rich (Type Ib) and
helium-poor (Type Ic) SNe reveals that they are statistically
indistinguishable, both in luminosity and decline rate. We report peak
absolute magnitudes of <MR≥-17.9±0.9 mag and
<MR≥-18.3±0.6mag for SNe Ib and Ic, respectively.
Description:
We used the robotic Palomar 60 inch telescope, in 2004-2007, to obtain
multi-epoch, multi-band optical observations (R-, V-bands) for our 25
SNe follow-up campaign.
