Gravitational radiation from compact binary systems: Gravitational waveforms and energy loss to second post-Newtonian order.
We derive the gravitational waveform and gravitational-wave energy flux generated by a binary star system of compact objects (neutron stars or black holes), accurate through second post-Newtonian order (O[(v/c)4] ∼ O[(Gm/rc)]) beyond the lowest-order quadrupole approximation. We cast the Einstein equations into the form of a flat-spacetime wave equation together with a harmonic gauge condition,...
متن کاملGravitational-radiation damping of compact binary systems to second post-Newtonian order.
The rate of gravitational-wave energy loss from inspiralling binary systems of compact objects of arbitrary mass is derived through second post-Newtonian (2PN) order O[(Gm/rc2)2] beyond the quadrupole approximation. The result has been derived by two independent calculations of the (source) multipole moments. The 2PN terms, and in particular the finite mass contribution therein (which cannot be...
متن کاملHigher Order Corrections in Gravitational Microlensing
We show that, in cosmological microlensing, corrections of order v/c ∼ ∆λ/λ, to the deflection angle of light beams from a distant source are not negligible and that all microlensing quantities should be corrected up to this order independently of the cosmological model used. keywords: microlensing, redshift, cosmology. In the last decade, gravitational lensing has become one of the most powerf...
متن کاملGravitational radiation from coalescing binary neutron stars.
We calculate the gravitational radiation produced by the merger and coalescence of inspiraling binary neutron stars using 3-dimensional numerical simulations. The stars are modeled as polytropes and start out in the pointmass limit at wide separation. The hydrodynamic integration is performed using smooth particle hydrodynamics (SPH) with Newtonian gravity, and the gravitational radiation is ca...
متن کاملGravitational Ionization: Periodic Orbits of Binary Systems Perturbed by Gravitational Radiation
The long term perturbation of a Newtonian binary system by an incident gravitational wave is discussed in connection with the issue of gravitational ionization. The periodic orbits of the planar tidal equation are investigated and the conditions for their existence are presented. The possibility of ionization of a Keplerian orbit via gravitational radiation is discussed.
