Description
The observation of gravitational waves from low mass compact objects (be it black holes or neutron stars) opens up the possibility to learn about nuclear physics at baryon densities above nuclear saturation and at very low temperatures. Interestingly, introducing non-trivial structure in the speed of sound sourced by changes in the degrees of freedom (possibly quarks) of ultra-dense matter can lead to extremely heavy neutron stars with interesting features and signatures in gravitational wave observables. I will here discuss these features and signatures and describe the prospects to constrain them with current and future gravitational wave detectors.
