The Caltech Core-Collapse Project:
Understanding the Population of Core-Collapse Supernovae


Highlights:

SN 2005E: a new type of supernova (Nature paper)

Two new CCCP papers: on SNe IIn and SNe Ib/c


The CCCP is a large observational study of core-collapse SNe. Uniform, high-quality NIR and optical photometry and multi-epoch optical spectroscopy have been obtained using the 200" Hale and robotic 60" telescopes at Palomar, for a sample of 50 nearby core-collapse SNe. The combination of both well-sampled optical light curves and multiepoch spectroscopy will allow to disentangle spectroscopically and photometrically based subtype definitions. Multi-epoch spectroscopy is crucial to identify transition events that evolve among subtypes with time (e.g., SNe IIb, initially similar to H-rich SNe II, but later evolving into H-poor and He-rich SNe Ib - several such events have been identified among the CCCP sample). The CCCP SN sample includes every corecollapse SN discovered between July 2004 and September 2005 that was visible from Palomar, found shortly (< 30 days) after explosion (based on available pre-explosion photometry), and was closer than ~120 Mpc. This complete sample allows, for the first time, a study of core-collapse SNe as a population, rather than as individual events.
