Abstract

Supernovae with a difference Two groups working independently report the observation of mildly relativistic outflows from seemingly ordinary type Ibc and type Ic supernovae. Soderberg et al. detected luminous radio emission from the type Ibc supernova SN 2009bb, implying an expansion velocity of 0.85 times the speed of light, and a minimum energy comparable to those of the radio afterglows of nearby γ-ray bursts. Paragi et al. observed mildly relativistic expansion (at 0.6 times the speed of light or more) for a small fraction of the ejecta from the type Ic supernova SN2007gr. These discoveries are relevant to the long-standing question of what makes a small fraction of supernova explosions eject material at relativistic speeds, producing the γ-ray bursts characteristic of the explosion of a massive star. Soderberg et al. conclude that only about 1% of type Ibc supernovae harbour central engines and Paragi et al. that most or all type Ic supernovae produce mildly relativistic jets, but as they account for only a small fraction of the total energy, they are very hard to detect.
