Effect of hyperons on f-mode oscillations in Neutron Stars

Abstract

As the densities in the interior of neutron stars exceed those of terrestrial nuclear experiments, they provide a scope for studying the nature of dense matter under extreme conditions. The composition of the inner core of neutron stars is highly uncertain, and it is speculated that exotic forms of matter such as hyperons may appear there. Gravitational waves emitted by unstable oscillation modes in neutron stars contain information about their interior composition and therefore allow us to probe the interior directly. Recently, a systematic investigation of f-mode oscillations in neutron stars revealed the role of the uncertainty in nuclear saturation parameters, particularly the effective nucleon mass, on its frequency. In this work, we study the influence of the appearance of hyperons on f-mode oscillation frequencies and therefore on the emission of gravitational waves. We also speculate whether a future detection of f-mode frequencies could provide a possibility of probing the presence of hyperons in the neutron star core.
