Axial Quasi-normal modes of Neutron Stars with Exotic Matter
Abstract
We investigate the axial w quasi-normal modes of neutron stars for 18 realistic equations of state in order to study the influence of hyperons and quarks on the modes. The study has been developed with a new method based on Exterior Complex Scaling with variable angle, which allow us to generate pure outgoing quasi-normal modes. A complete study of the junction conditions has been done. We have obtained that w-modes can be used to distinguish between neutron stars with exotic matter and without exotic matter for compact enough stars.
