| Abstract : | The nature of matter at high density is still debated; mostly about if it is smooth or if it has a discontinuity. In this work, we try to differentiate agnostically constructed equations of state of two types: one smooth and the other discontinuous, using f-mode bounds and universal relations obtained from neutron stars. We find that there is some excluded region in the f-mode frequency and in its damping time for the two generically different families which can be exploited to differentiate the regions. We also find that one needs a full general relativistic calculation to find these excluded regions as the relativistic Cowling approximation can give substantially different excluded regions. It was also seen that the universal relation between f − Λ and τ − Λ for full general relativistic calculation was more accurate; however, it is difficult to differentiate between the two families considering the universal relation. |
