Abstract: We explore the possible formation of ordered phases in neutron star matter.In the framework of a quantum hadrodynamics model where neutrons, protons and Lambda hyperons interact via the exchange of mesons, we compare the energy of the usually assumed uniform, liquid phase, to that of a configuration in which di-lambda pairs immersed in an uniform nucleon fluid are localized on the nodes of a regular lattice.The confining potential is calculated self-consistently as resulting from the combined action of the nucleon fluid and the other hyperons, under the condition of beta equilibrium.We are able to obtain stable ordered phases for some reasonable sets of values of the model parameters.This could have important consequences on the structure and cooling of neutron stars.
