Query: Finite volume of baryons and the mass limit for neutron stars   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.
