Finite volume of baryons and the mass limit for neutron stars
Qi-Ren Zhang, Bo-Qiang Ma, Walter Greiner
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.
