star tidal waves may signal impending mergers

Researchers have found a new way to detect some of the most cataclysmic mergers

 the extremely dense cores of massive dead stars, spiraling toward each other or into a black hole

Those tidal waves reveal themselves through regular flashes of electromagnetic radiation

they're just lots and lots of gravity. In contrast, neutron stars are essentially gigantic atomic nucle

A typical neutron star is only a few kilometers across yet can weigh up to a few times the mass of the sun

The interiors of neutron stars are the most mysterious, since the pressures and densities

the neutrons themselves break down into their component quarks.
