Dense Matter EoS


The composition and interactions of matter above nuclear saturation density still pose a great challenge to nuclear physics. We show  in the figure below a large number of proposed EoS, including nucleonic and quark EoS, mean-field models, and those including hyperons and condensates.


Here are the links to a tar file with these EoS in tabular form and a tar file for the corresponding mass-radius relations. You can find README files in both folders with descriptions of the tables and the references for each EoS.




Astrophysical observations of neutron star radii and masses, combined with the constraints from low density nuclear physics experiments provide tight constraints on the dense matter EoS. The empirically determined region that is in agreement with all current constraints is shown in blue.



Earlier compilations and naming conventions are from Lattimer & Prakash 2001 and Read et al. 2009. The full list included above is from Ozel & Freire 2016.
