Talk:- Studying the Tidal Deformability of Compact Stars Through Gravitational Wave from Binary Mergers: The Effect of Including Post-Merger Phase

The recent discoveries of binary black holes by gravitational-wave detection hint at the opportunity of detecting gravitational-wave signals from binaries consisting of compact stars. Binaries typically undergo three stages during coalescence: inspiral, merger and post-merger. Information on the compact stars’ matter is encoded throughout the gravitational-wave signal, detections of the signal can constrain the equation of state of ultradense matter. The feasibility of constraining the equation of state through gravitational-wave detections by second and future generation detectors have been studied using the inspiral and post-merger stages separately. We present the effect and the possible improvement in constraining the equation of state by using a toy model of binary mergers, which consists of inspiral and post-merger.
