Phys. Rev. Lett. 51, 1019–1021 (1983)Gravitational Radiation Reaction in the Binary Pulsar and the Quadrupole-Formula ControversyReceived 31 May 1983; published in the issue dated 19 September 1983 The evolution of the orbit of a binary pulsar under the action of gravitational radiation reaction is calculated. No approximation is made of weak gravity inside the individual stars; the details of the orbital motion are given directly (to order c-5 and G3). The calculation reveals no acceleration of the center of mass of the system, and a secular decrease of the time of return to periastron. The quantitative results agree both with the well-known "quadrupole formula" and with observations. © 1983 The American Physical Society URL:
