I will summarize our current understanding for possible mass ejection process in the merger of binary neutron stars and in the post merger phase.

In the coalescence of compact objects, not only the properties of the objects and the distorted spacetime close to them are important, but the far-field behaviour is also relevant: it is at infinity that the study of global properties of spacetimes and unambiguous gravitational wave extraction are possible. A convenient way of including infinity in numerical relativity simulations is...

389. Compact object formation in extreme core-collapse supernovae

Extreme core-collapse supernovae belong to the most energetic transients in the universe and are birth sites of compact objects like neutron stars and black holes. I will discuss the unique challenges in both input physics and computational modeling for these systems involving all four fundamental forces and highlight recent breakthroughs in full 3D simulations. I will pay particular...

390. The physics and astrophysics of neutron-star binaries: a report from Frankfurt

Luciano Rezzolla

20/06/2017, 16:15

I will argue that if black holes represent one the most fascinating implications of Einstein's theory of gravity, neutron stars in 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...
