Abstract:
Supernovae are stellar explosions driven by gravitational or
thermonuclear energy that is observed as electromagnetic radiation
emitted over weeks or more. In all known supernovae, this radiation
comes from internal energy deposited in the outflowing ejecta by one
or more of the following processes: radioactive decay of freshly
synthesized elements (typically 56Ni), the explosion shock in the
envelope of a supergiant star, and interaction between the debris and
slowly moving, hydrogen-rich circumstellar material. Here we report
observations of a class of luminous supernovae whose properties cannot
be explained by any of these processes. The class includes four new
supernovae that we have discovered and two previously unexplained
events (SN 2005ap and SCP 06F6) that we can now identify as members
of the same class.
