Quark-Hadron Phase Transition with Finite-Size Effects in Neutron Stars

Abstract: We study the quark-hadron phase transition with the finite-size effects in neutron stars. The finite-size effects should be, generally, taken into account in the phase transition of multi-component system. The behavior of the phase transition, however, strongly depends on the quark model, hadron model, surface tension, neutrino fraction, and temperature. We find that, if the surface tension is strong, the EOS becomes to be close the one with the Maxwell condition for any hadron and/or quark models, though we adopt the Gibbs conditions. We also find that the mass-radius relations by the EOS are consistent with the observations, and our model is, then, applicable to realistic astrophysical phenomena such as the thermal evolutions of compact stars.
