The binary system will end in a massive, gold-forming explosion.
“We know that the Milky Way contains at least 100 billion stars and likely hundreds of billions more. This remarkable binary system is essentially a one-in-ten-billion system,” said André-Nicolas Chené in a
. Chené is a NOIRLab astronomer and an author on the study. “Prior to our study, the estimate was that only one or two such systems should exist in a spiral galaxy like the Milky Way.”powerful supernova when they die, the dying star in CPD-29 2176 is becoming an ultra-stripped supernova. An ultra-stripped supernova lacks the vast amount of force that a typical supernova has,stripped by its companion.
. “To one day create a kilonova, the other star would also need to explode as an ultra-stripped supernova so the two neutron stars could eventually collide and merge.”

At the time, the star system, named HR8799 was known to have three planets, but follow-up observations a year later revealed a fourth world.
