摘要

We explore the effects of the density dependence of symmetry energy on the crust-core phase transition and dynamical instabilities in cold and warm neutron stars in the relativistic mean field (RMF) theory with point-coupling interactions using the Vlasov approach.The role of neutrino trapping is also considered.The crust-core transition density and pressure,distillation effect,and cluster size and growth rates are discussed.The present work shows that the slope of symmetry energy at saturation,temperature,and neutrino trapping have non-negligible ef-fects.
