Description
The observation of gravitational waves from neutron stars opens up the possibility to learn about Quantum Chromodynamics 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 unusual tidal deformabilities that lead to specific signatures in gravitational wave observables [1]. Here, I will discuss these signatures and describe their measurability with current and future gravitational wave detectors.
