Binary neutron stars: Einstein's richest laboratory



Prof. Luciano Rezzolla (click here)

Chair of Theoretical Astrophysics, Institute of Theoretical Physics, Frankfurt




Abstract: I will argue that if black holes represent one of the most fascinating implications of Einstein's theory of gravity, neutron stars in a binary system are arguably its richest laboratory, where gravity blends with astrophysics and particle physics. I will discuss the rapid recent progress made in modelling these systems and show how the inspiral and merger of a binary system of neutron stars is more than a strong source of gravitational waves. Indeed, while the gravitational signal can provide tight constraints on the equation of state for matter at nuclear densities, the formation of a black-hole--torus system can explain much of the phenomenology of short gamma-ray bursts, while the ejection of matter during the merger can shed light on the chemical enrichment of the universe.
