Maximally model independent equation of state for neutron star matter
We develop a theoretical approach to reconstruct equation of state (EOS) that can incorporate the inherent observational errors in the data of individual neutron stars. If the errors are large, the reconstructed EOS would lie in a band in the pressure-energy density plane. With more observed stars, their properties and progressively smaller errors, a unique curve could be obtained. Instead of pressure as a function of density, in our analysis we take advantage from using the squared adiabatic speed of sound. |
