Finite volume of baryons and the mass limit for neutron stars

Abstract

We confirmed the following idea by numerical calculation: The extended structure of baryons may make the nuclear equation of state stiffer at higher density while keeping the compression modulus for normal nuclear matter around its empirical value $K=240MeV$.The model built in this wayy fits all empirical data for normal nuclear matter and gives the mass limit of neutron stars compatible with the observation.
