Abstract: This paper describes the Primary-centric Framework conceived by the Author for describing first order binaries or higher order binaries. This paper gives the formation and evolution process of the Pulsar-Neutron Star System by common envelope evolution and by dynamical coupling. The discovery of the Hulse-Taylor Pair is described. Its impact in terms of universal orbital decay, periastron advance and its effect on astrophysical landscape is described. The Binary Neutron Stars discovered till date are tabulated. The underlying physics of Gravitational Wave Radiation is unveiled and the impact it has on the Binary System in terms of inspiral, ringdown,chirp signal and final merger is described and the aftermath of merger is also described. This study points to the possibility of using Binary Neutron Star (BNS) as a probe for extreme gravity and quantum gravity.

Keywords: dipole radiation; quadrupolar radiation: inspiral: chirp signal: merger; gamma bursters.
