| Abstract: |
We study the effect of differential rotation and of stiffness
of equation of state (EOS) on the maximum allowed mass of neutron
stars. We numerically construct stellar models using a highly
accurate relativistic code which allow us to calculate rotating
neutron stars for broad ranges of masses and degrees of differential
rotation. We find various types of solutions, which haven't been
considered in previous works based on other algorithms, mainly due
to numerical limitations. We show that depending on the degree of
differential rotation and the equation of state the maximum allowed
mass of neutron stars can be 0.5–4 times larger than the
corresponding non-rotating value. The largest maximum mass increases
were obtained for moderately stiff EOS and new types of models. |
