    Abstract:
    Set of neutron star observational results is used to test some selected
    equations of state of dense nuclear matter. The first observational
    result comes from the mass-baryon number relation for pulsar B of the
    double pulsar system J0737-3039. The second one is based on the
    mass-radius relation coming from observation of the thermal radiation of
    the neutron star RX J1856.35-3754. The third one follows the population
    analysis of isolated neutron star thermal radiation sources. The last
    one is the test of maximum mass. The equation of state of asymmetric
    nuclear matter is given by the parametrized form of the relativistic
    Brueckner-Hartree-Fock mean field, and we test selected parametrization
    that represent fits of full relativistic mean field calculation. We show
    that only one of them is capable to pass the observational tests. This
    equation of state represents the first equation of state that is able to
    explain all the mentioned observational tests, especially the very
    accurate test given by the double pulsar even if no mass loss is
    assumed.
