| Abstract : | Many aspects of dense nuclear matter can be known from the compact objects such as
neutron stars (NSs). Gravitational waves (GWs) detected from binary compact star merger
events (GW170817, GW190425) and subsequent estimations of tidal deformability play
a key role in constraining the behaviour of dense matter at high density regimes. Massive compact star candidates, with mass ∼ 2M⊙ set strict bounds on the dense matter equation of state. The possibility of heavier strange and non-strange baryons inclusion constrain the theoretical models of nuclear matter comportment at large density regimes. The quasi normal oscillation modes detectable by future GW detectors emitted from the astrophysical events such as core-collapse supernovae, binary NS merger remnant can play another important role in ascertaining the properties of dense matter.
In this work, we investigate the inferences of the finite temperature scenarios as mentioned
above on oscillation modes. We consider the phenomenological DD2 coupling model to describe the dense nuclear matter and its extension to exotic degrees of freedom within the Cowling approximation to get a first-hand qualitative knowledge. It is found that the pressure modes are much more sensitive in the thermal picture, as compared to the zero temperature scenario. We also compare the results derived from the Γ−law with the realistic finite temperature equation of states. |
