The team estimates that half of those are merging and might explode as supernovae in the astronomically near future.
"These are weird systems - objects the size of the Earth orbiting each other at a distance less than the radius of the Sun," said Smithsonian astronomer Warren Brown, lead author of the two papers reporting the find
