Abstract

For the theorist, Type Ib and Ic supernovae are the explosion of massive stars that have lost their hydrogen envelopes. For the observer, Type Ib supernovae are those that show no evidence of hydrogen, a weak or absent Si II absorption feature near 6150 A at peak light, and strong oxygen emission at late times. The light curves of Type Ib are also about four times fainter and somewhat broader than Type Ia. Unlike Type la, Type Ib supernovae can be strong radio sources and show a strong preference for star forming regions in spiral galaxies. No Type Ib supernova has ever been discovered in an elliptical galaxy. Type Ic greatly resembles Ib, but additionally is characterized by a weak or absent He feature at 5876 A and, in at least one case, a narrower light curve.
