  In this paper we present a simple discussion on the properties of compact
stars using an EoS obtained in effective field theory anchored on scale and
hidden-local symmetric Lagrangian endowed with topology change and a
unequivocal prediction on the deformation of the compact star, that could be
measured in gravitational waves. The objective is not to offer a superior or
improved EoS for compact stars but to confront with a forthcoming astrophysical
observable the given model formulated in what is considered to be consistent
with the premise of QCD. The model so obtained is found to satisfactorily
describe the observation of a 2-solar mass neutron star with a minimum number
of parameters. Specifically the observable we are considering in this paper is
the tidal deformability parameter (equivalently the Love number k_2), which
affects gravitational wave forms at the late period of inspiral stage. The
forthcoming aLIGO and aVirgo observations of gravitational waves from binary
neutron star system will provide a valuable guidance for arriving at a better
understanding of highly compressed baryonic matter.
