kilonova (яркая, в 1000 раз ярче новой, это только 1/10 – 1/100 яркости средней сверхновой; Kilonovas are swift, brilliant explosions that occur during the merger of neutron stars, which are ultradense remnants of collapsed stars that are composed almost entirely of neutrons, or uncharged particles. Collisions between neutron stars are thought to be 1,000 times brighter than a typical supernova, and they are the universe’s primary source of such elements as silver, platinum and gold. // Washington Post, 2017 Alex_Odeychuk) |
