Supernovae are generally believed to be triggered either in the core collapse of a massive star or in the increase of mass that a white dwarf star accumulates from a stellar companion (through accretion or merger), but a long-standing puzzle surrounding Type II supernovae is why the compact object remnant after the explosion gains a large velocity away from the core. Another unresolved problem of supernova is how to determine high rotating neutron stars that are ascribed to be a skillful kick from asymmetric collapse of a massive star, but the mechanism of this asymmetry is still unknown. Here we propose that due to orbital shrinkage the two stars of a binary star system may finally take place a smashing collision to form a supernova. The simulation of white dwarfs RX J0806.3+1527 in principle fits to the observed features of supernova.
