Possible tidal dissipation in millisecond pulsar binaries

Aims. The post-Keplerian(PK) parameters inferred from pulsar timing provide a convenient way to test Einstein’s general theory of relativity. However, before obtaining pure orbital decay Ṗb induced by gravitational wave radiation, which is one the PK parameters, number factors need be accounted for carefully. effect tidal dissipation on has been thought as negligible. Here, we investigate data possible effects Ṗb.
