Post-Newtonian Theory for Precision Doppler Measurements of Binary Star Orbits
نویسنده
چکیده
The determination of velocities of stars from precise Doppler measurements is described here using relativistic theory of astronomical reference frames so as to determine the Keplerian and post-Keplerian parameters of binary systems. Seven reference frames are introduced: (i) proper frame of a particle emitting light, (ii) the star-centered reference frame, (iii) barycentric frame of the binary, (iv) barycentric frame of the Galaxy, (v) barycentric frame of the Solar system, (vi) geocentric frame, and (vii) topocentric frame of observer at the Earth. We apply successive Lorentz transformations and the relativistic equation of light propagation to establish the exact

Relativistic precession around rotating neutron stars: Effects due to frame-dragging and stellar oblateness
General relativity predicts that a rotating body produces a frame-dragging (or LenseThirring) effect: the orbital plane of a test particle in a non-equatorial orbit precesses about the body’s symmetry axis. In this paper we compute the precession frequencies of circular orbits around rapidly rotating neutron stars for a variety of masses and equations of state. The precession frequencies comput...
متن کاملLorentz Covariant Theory of Precise Doppler Mea - surements
Abstract. The Lorentz covariant theory of precise Doppler measurements (PDM) based on the retarded Liénard-Wiechert solution of the Einstein equations is described. An exact solution of equations of light propagation in the field of arbitrary moving bodies, which drastically extends the range of applicability of the new theory of PDM, is obtained. An explicit formula for the gravitational shift...

متن کاملBinary Neutron-Star Systems: From the Newtonian Regime to the Last Stable Orbit
We report on the first calculations of fully relativistic binary circular orbits to span a range of separation distances from the innermost stable circular orbit (ISCO), deeply inside the strong field regime, to a distance (∼ 200 km) where the system is accurately described by Newtonian dynamics. We consider a binary system composed of two identical corotating neutron stars, with 1.43 M gravita...
متن کاملGravitational 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,...
