Type 1a (6)

The light from the explosion is 15 billion times brighter than the sun (this is why we can see them from halfway across the universe). The white dwarf is completely obliterated. And what about the red giant? The outer atmosphere is swept away and, with the companion that held it in its orbit obliterated, the core of the red giant shoots off into space.
