The structure and composition of Neutron Stars (NS) is an open problem in Physics. The Equation of State (EoS) of matter in NS cores is very uncertain because there is a lack of knowledge about how matter behaves at such very high energy.
The aim of our work is to predict some observables that may impose constraints on the EoS, at present limits are obtained mainly through the mass-radius relationship, but in the near future we expect to obtain stronger constraints with the Gravitational Waves (GW) that LIGO and VIRGO may observe.
We computed the Quasi-Normal-Mode (QNM) oscillations of NSs assuming some EoSs, mainly we can divide the EoS used as NS and Strange Stars (SS). Specifically we computed the frequency of the fundamental mode and the first pressure mode and we found that these frequencies strongly depend on the EoS used. We found that different compositions relate to different kinds of frequencies.
These predictions may allow to distinguish mainly between NSs and SSs, and then it will be possible to understand if SS actually exist, since as of today they are hypothetical stars. |
