Flashes from neutron star tidal waves may signal impending mergers


Researchers have found a new way to detect some of the most cataclysmic mergers in the universe before they happen.

Neutron stars, the extremely dense cores of massive dead stars, spiraling toward each other or into a black hole can raise tidal waves in the oceans of heavy charged particles surrounding the neutron stars. Those tidal waves reveal themselves through regular flashes of electromagnetic radiation, which can serve as an early warning system for impending mergers, the researchers found.
