Einstein Probe's X-ray vision discovers an 'impossible' pair of vampire stars
71% Informative
A flash of powerful X-ray light coming from a nova explosion on a white dwarf star has caught the attention of astronomers using the ChineseEuropean Einstein Probe .
This nova is especially exciting because it is found in a particularly unusual binary star system.
One of the stars is called a "Be" star, totaling about 12 times the mass of our sun.
A star of 12 solar masses should explode as a supernova after just 20 million years .
Type Ia supernova explosions spur the destruction of white dwarf stars that have accreted too much mass.
The limit is 1.44 times the mass of our sun; it won't take too much accretion to push this white dwarf over the edge.
Its only chance to survive relies on its 12 -solar-mass companion exploding first .
