PTF 11kx is an example of one of these events, which can be modelled using the CMAGIC relation. Some anomalous versions of these events may be explained by their having doubly-degenerate precursors. A cataloguing of 32 of these events in the Calan/Tololo survey gave an important relation describing them, which fits a curve using the delta-m-15 value. The Dark Energy Survey hopes to catalogue several thousand of these phenomena, which were used by Reiss, Perlmutter, and Schmidt to show that q is negative and the (*) expansion of the universe is accelerating. These events have a maximum absolute magnitude of 19.3, and the decay of cobalt-56 powers the near-infrared shoulder of their light curves, which are modelled by the Phillips relationship. These events, which have silicon II lines but no Balmer lines, occur whe

These events, which have silicon II lines but no Balmer lines, occur when carbon detonation is triggered by accretion of a binary partner, and the fact that these events have a consistent peak luminosity allows their use as standard candles.. For 10 points, name this event in which a white dwarf collapses into a neutron star.
