Title:  [Journal Club] Degeneracy in the inference of phase transitions in the neutron star equation of state from gravitational wave data
Venue:  P7A
Speaker:  Dr. Hung Tang
Institution:  Academia Sinica
Abstract:  

Gravitational wave (GW) detections of binary neutron star inspirals will be crucial for constraining
the dense matter equation of state (EoS). We demonstrate a new degeneracy in the mapping from
tidal deformability data to the EoS, which occurs for models with strong phase transitions. We find
that there exists a new family of EoS with phase transitions that set in at different densities and
that predict neutron star radii that differ by up to ∼ 500 m, but that produce nearly identical tidal
deformabilities for all neutron star masses. Next generation GW detectors and advances in nuclear
theory may be needed to resolve this degeneracy.
