Frankenstein star could be on the brink of a startling transformation


The discovery of a moon-size zombie star transforming into another type of stellar corpse could upend astronomers’ understanding of how stars evolve. 

The cosmic zombie — an embering core of a dead star, or a white dwarf — is about the size of Earth’s moon, making it the smallest white dwarf ever found. Despite being tiny, with a radius of 2,670 miles (4,300 kilometers) compared to our sun’s 432,470-mile (696,000 km) radius, the stellar corpse has a ginormous mass of about 1.35 times that of the sun.
