Critical behaviour in the head-on collision of rotating relativistic neutron stars

Natascha Wechselberger, ITP, Frankfurt

Critical phenomena can be observed in several physical processes, one of them being the head-on collision of neutron stars. By critical phenomena we mean that solutions close to the black hole formation threshold show special properties such as universality, time-independence or scale-independence. These phenomena are an interesting field of study since they can be used to investigate fundamental properties of general relativity such as the cosmic censorship hypothesis. In this talk I will present the results of my master thesis concerning, in particular, the collision of uniformly rotating neutron stars.
