Bayesian Analysis for Extracting Properties of the Nuclear Equation of State from Observational Data Including Tidal Deformability from GW170817â€
Round 1
Reviewer 1 Report
This article studies a family of cold QCD matter equations of state,
applying Bayesian statistical analysis to recent observational
gravitational radiation data on a neutron star merger. The candidate
equation of state contains a first order phase transition and the
analysis bounds parameters of the transition. Nobody can today
conclusively say whether this is the correct EoS, but this is meaningful
work and a step forward. The article deserves being published.

We thank the reviewer for supporting the publication of our investigation.
We have improved the text and also the Figures, we added the left panel to Fig. 2.
We updated also the references with a few recent entries.
Reviewer 2 Report
The authors study the existence of a pair of stars with approximate the same mass but different radious,the larger composed by hadronic matter whereas the smaller one being a hybrid star with a quark matter core.There are several studies of the EoS of such systems but they have not taken into account the new data coming from the event GW170817.The authors do a Bayesian analysis including such event in addition to previous requirements.The results support the existence of an early phase transition, taking place at twice the normal muclear density.The study and the main result is interesting touching a hot topic.
The Inclusion of the event GW170817 in the study of the EoS was mandatory for the field and therefore is welcome.The result is interesting,I recommend the publication
