Usually, the merger creates a supernova, but new research concludes that two separate and unusual white dwarfs are best explained as merger remnants.

In the vastness of the Universe, any new object with interesting properties can spur the search for similar objects, potentially establishing a new class of stars.

According to the team, these two remnants are sufficient to define a new class of stars.
