Assessment of Neutron Star Equation of State by Gravitational Waves

The possibility of assessing the equation of state of the neutron star matter using gravitational waves is briefly sketched. The effective theory recently proposed in the frame work of the scale-invariant hidden local symmetry is discussed to demonstrate its particular feature of a change over in EoS from lower density to higher density. The possible implications on the gravitational waves from coalescing binary neutron stars are discussed.
