Description

We provide equations of state (EoS) for matter at attainable densities in physical neutron stars at zero and finite temperature. These EoS are derived from current knowledge of the uncertainty bands of chiral effective field theories and pQCD constraints. The results are independent of neutron star observations and can be used to test general relativity as well as theories beyond GR, such as modified gravity. We show some results and their application to calculate the specific latent heat in a first-order phase transition. In addition, we use the EoS band to solve the Tolman-Oppenheimer-Volkoff (TOV) equations in GR and Palatiny f(R) gravity.
