Density Discontinuity of a Neutron Star and Gravitational Waves

Abstract

We calculate quasi-normal f- and g-modes of a neutron star with density discontinuity, which may appear in a phase transition at extreme high density. We find that discontinuity will reflect largely on the f-mode, and that the g-mode could also be important for a less massive star.Comment: REVTeX,18 pages, 8 figure
