Universal relations for quasi-normal modes of realistic neutron stars containing exotic matter. |
|
Abstract |
We analyze the quasinormal mode spectrum of realistic neutron stars by studying axial and polar modes. We consider different equations of state satisfying the 2M⊙ constraint, most of them containing exotic matter. New phenomenological relations between the frequency and damping time of the modes are obtained. These new relations are independent of the equation of state and relate the quasi-normal mode spectrum to the global properties of the star. Hence they could be used to constrain the equation-of-state of neutron stars. Also, We present new Universal relations between quasi-normal modes and I-LOVE-Q parameters for neutron stars including exotic mater. |
