SUMMARY: Using the Hubble Space Telescope, astronomers have located what they think is the burned out star at the heart of Tycho's Supernova Remnant, which exploded in 1572. This discovery provides the first direct evidence that these kind of supernovae, called Type 1a, occur when a white dwarf consumes material from a binary companion until it reaches a certain point and explodes. They discovered the star, which is similar to our own Sun, because it's moving away from the explosion three times faster than other objects in the region - it was sling shotted away when its dancing partner vapourized.

Could this be a case of "flying jennied" away as opposed to sling-shotted? If the center of mass of the exploded partner hasn't moved appreciably, why would the partners disappearance produce the effect observed?
