Our EoS are constrained only by input from hadron physics and fundamental principles, without feedback from neutron star observations, and so without relying on general relativity (GR). They can therefore be used to test GR itself, as well as modified gravity theories, with neutron star observables, without logical circularity. We have adapted state of the art results from NN chiral potentials for the low-density limit, pQCD results for the asymptotically high-density EoS, and use monotony and causality as the only restrictions for intermediate densities, for the EoS sets to remain as model-independent as is feasible today.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttp://dx.doi.org/10.1088/1361-6471/ab2567https://iopscience.iop.org/open access53Neutron star equation of stateTests of general relativityEquation of state.Física (Física)22 Física
