Abstract
An analytic parametrization of the cold hypernuclear matter equation of state based on microscopic Brueckner–Hartree–Fock calculations is constructed using realistic nucleon-nucleon and hyperon-nucleon interactions. The parametrization is based on a simple phase-space analysis and reproduces with good accuracy the results of the microscopic calculations with a small number of parameters. This parametrization allows for rapid calculations that accurately mimic the microscopic results, being therefore very useful from a practical point of view. As an example, we determine the composition and some properties of neutron stars, such as mass-radius relation, tidal deformability and moment of inertia, using the equation of state derived from this parametrization.
