Abstract:
We present a densely sampled, homogeneous set of light curves of 64
low-redshift (z≲0.05) stripped-envelope supernovae (SNe of Type IIb,
Ib, Ic, and Ic-BL). These data were obtained between 2001 and 2009 at
the Fred L. Whipple Observatory (FLWO) on Mount Hopkins in Arizona,
with the optical FLWO 1.2m and the near-infrared (NIR) Peters
Automated Infrared 1.3m telescopes. Our data set consists of 4543
optical photometric measurements on 61 SNe, including a combination of
UBVRI, UBVr'i', and u'BVr'i', and 1919 JHKs NIR measurements on 25
SNe. This sample constitutes the most extensive multi-color data set
of stripped-envelope SNe to date. Our photometry is based on
template-subtracted images to eliminate any potential host-galaxy
light contamination. This work presents these photometric data,
compares them with data in the literature, and estimates basic
statistical quantities: date of maximum, color, and photometric
properties. We identify promising color trends that may permit the
identification of stripped-envelope SN subtypes from their photometry
alone. Many of these SNe were observed spectroscopically by the
Harvard-Smithsonian Center for Astrophysics (CfA) SN group, and the
spectra are presented in a companion paper. A thorough exploration
that combines the CfA photometry and spectroscopy of stripped-envelope
core-collapse SNe will be presented in a follow-up paper.
Description:
All optical photometry presented in this paper was obtained with the
FLWO 1.2m telescope during the CfA3 (Hicken et al. 2009,
Cat. J/ApJ/700/331) and CfA4 campaigns (Hicken et al. 2012,
Cat. J/ApJS/200/12). Three different cameras were used to acquire the
photometry: the 4Shooter 2x2 CCD mosaic (for data before 2004
September), the Minicam CCD mosaic camera (2004 September until 2005
July), and the Keplercam CCD mosaic camera (after 2005 August). All
UBV photometry is obtained in Johnson UBV, with B and V Harris
filters. At redder wavelengths, observations were conducted with the
4Shooter 2x2 CCD mosaic in Johnson RI band passes with the Harris
filter set and after 2004 September with Sloan Digital Sky Survey
(SDSS) r'i' filters. The typical FWHM in our data falls between 1.5"
and 3", with the larger values typically found in the CfA4 survey.
For 25 SNe in our sample, we obtained NIR photometry with the fully
automated 1.3m PAIRITEL located at FLWO, in JHKs. The effective seeing
generally fell between 2" and 2.5" FWHM.
