Data details dynamically driven double-degenerate double-detonation supernova theory
The identification of three white dwarf stars zooming at hyper-fast velocities might provide evidence to support an alternative theory explaining the formation of Type 1a supernovae, researchers say. Type 1a supernovae, orthodoxy holds, arise when two white dwarf stars locked in a binary orbit merge with each other, kick-starting a runaway nuclear fusion reaction and consequent massive explosion.
