Abstract. We have studied the possible existence of pasta phases in the inner crust of neutron stars using the Compressible Liquid Drop Model and the Thomas-Fermi method with Skyrme forces. Special attention is payed to the search of the density corresponding to the crust-core transition. Some properties of this transition, namely density and pressure, are also estimated from the core side using the thermodynamical and dynamical methods. Finally we analyze the impact of the slope of the symmetry energy on the aforementioned properties of the crust-core transition.
