Effects of relativistic parameter sets on tidal deformabilities and f-mode oscillations of neutron stars
文献摘要：
The implications of relativistic parameter sets established at saturation density on the tidal deformabilities and f-mode oscillations of neutron stars(NSs)are examined using constraints from the gravitational wave(GW)event GW170817 and NICER.According to our findings,the isovector saturation parameters have a greater impact on the radii and tidal deformabilities of NSs than the isoscalar saturation parameters.Our analysis also examines the impact of saturation properties on f-mode frequencies and finds that f-mode frequencies with 1.4 M☉(solar mass)are roughly between 1.95 and 2.15 kHz.These findings could be confirmed by future advanced GW detectors.A good linear parameter-independent correlation between f-mode frequencies inferred from saturation parameters in the entire region is also observed,and we attempt to fit an updated version of this universal relationship.Furthermore,we used chiral effective theory(xEFT)together with the multi-messenger astronomy constraints to further reinforce the rationality of the conclusions we have reached.
