Binary neutron stars may generate gravity waves when they combine


Gravity waves are the ripples of spacetime predicted by Einstein's theory of general relativity, and are expected to be emitted from the energetic mergers of large astrophysical objects such as binary neutron stars or binary black holes. Several large detector systems are trying to observe gravity waves. Helping that effort, Bernuzzi et al. introduce an accurate model of the dynamics of such mergers. Understanding the details of the mergers, taking into account the contribution of strong gravity and tidal disruption in the evolution from a binary to a merged system and the resulting changes in the waveforms of the gravity waves, should provide crucial insights into the makeup of our universe.
