New-found 'failed' star orbits 'dead' star every 71 mins
Astronomers have discovered a rare binary system consisting of a body that "failed" to generate enough fusion to become a star, called a brown dwarf, and a "dead" fuel-exhausted stellar remnant, a white dwarf. Scientists found they orbit each other at 100 km/sec, completing an orbit in 71 minutes, further the white dwarf would "cannibalise" the brown dwarf in future.
