Description
This talk examines the impact of nonconvex equations of state (EoS) in binary neutron (BNS) star merger simulations. We extended the work GR et al. 2024 addressing the key distinction between first-order and crossover phase transitions (PT) in the context of the quasi-universal relation $f_{peak}-\Lambda$. We develop a parametrized PT that allows control of its stiffness and convexity. By analyzing the emitted gravitational-wave, we compare the results from different PTs. Outliers in the quasi-universal relation may signal the presence of general nonconvex behavior in the EoS.
