Description

With the detection of GW170817 we have observed the first multi messenger signal
from two merging neutron stars. This signal carried a multitude of information
about the underlying equation of state of nuclear matter.
I will demonstrate how this observation can be used
to constrain macroscopic properties of neutron stars, in particular the radius and the maximum mass and hence to set limits on the equation of state. I will also comment on the possibility of how we can use future gravitational wave detections in order to set limits on the existence of twin stars.
Finally, I will briefly comment on the detectability of a quark-hadron phase transition in a neutron star merger event.
