Impact of neutron star crust on gravitational waves from the axial  w-modes

doi:10.1088/1674-1056/20/6/060402

Abstract The imprints of the neutron star crust on the gravitational waves emitted from the axial w-modes are investigated by adopting two typical equations of state (EOSs) of the crust matter and two representative EOSs of the core matter. It is shown that there is a significant effect of the crust EOSs on the gravitational waves from the axial w-mode oscillation for a stiff core EOS.

Keywords: equation of state neutron star gravitational waves
