Deviations from γ=1 in the Zipoy-Voorhees metric shift the (z,w,v) classification of periodic orbits and induce phase shifts plus amplitude modulations in their gravitational-wave signals.
Scalar couplings in Freund-Nambu gravity shift ISCO inward and produce detectable temporal dephasing in EMRI gravitational wave bursts while preserving orbit topology.
Quintessence shifts orbital radii, turning points, and zoom-whirl parameters for timelike geodesics around a magnetically charged black hole, producing burst-like gravitational waveforms whose phase, timing, and millihertz spectra are modified by the quintessence coupling.
The quantum parameter ξ in an asymptotically safe regular black hole shifts the innermost stable orbit, enhances whirl behavior in periodic geodesics, and produces amplitude-modulated millihertz gravitational-wave strains whose peak amplitude grows with ξ, placing them inside the sensitivity bands预计
Gravitational waveforms from periodic orbits and QPOs around ENLMY black holes are derived and used with MCMC to constrain the Yukawa parameter and charge for microquasars and the galactic center.
Periodic orbits around a non-rotating Destounis-Suvorov-Kokkotas black hole are taxonomized with integer triplets and their gravitational waveforms are calculated, showing that large deformations eliminate circular orbits and modify wave signals.
