Scientists have discovered an extremely rare star system that is doomed to explode in a 'kilonova' caused by the merger of two neutron stars.
For the first time, scientists have discovered a double-star system that is doomed to explode in a fiery"kilonova," a precious-metal-creating blast caused by the merger of two stellar corpses.
"We know that the Milky Way contains at least 100 billion stars and likely hundreds of billions more," André-Nicolas Chené , an astronomer at the National Science Foundation's NOIRLab, said in a statement ."This remarkable binary system is essentially a one-in-ten-billion system. Prior to our study, the estimate was that only one or two such systems should exist in a spiral galaxy like the Milky Way.
Chené and his colleagues used the SMARTS 1.5-meter Telescope at the Cerro Tololo Inter-American Observatory in Chile to discover the star system CPD-29 2176, located about 11,400 light-years from Earth. The team deduced that the binary star system contained a small, dense neutron star being orbited by a massive companion star that will likely collapse into a neutron star, itself, in the distant future.
