High-order post-Newtonian contributions to the two-body gravitational interaction potential from analytical gravitational self-force calculations
Donato Bini, Thibault Damour
We extend the analytical determination of the main radial potential describing (within the effective one-body formalism) the gravitational interaction of two bodies beyond the 4th…
Deviation of quadrupolar bodies from geodesic motion in a Kerr spacetime
Donato Bini, Andrea Geralico
The deviation from geodesic motion of the world line of an extended body endowed with multipolar structure up to the mass quadrupole moment is studied in the Kerr background accord…
Tidal indicators in the spacetime of a rotating deformed mass
Donato Bini, Kuantay Boshkayev, Andrea Geralico
Tidal indicators are commonly associated with the electric and magnetic parts of the Riemann tensor (and its covariant derivatives) with respect to a given family of observers in a…
Equatorial Circular Geodesics in the Hartle-Thorne Spacetime
Donato Bini, Kuantay Boshkayev, Remo Ruffini +1
We investigate the influence of the quadrupole moment of a rotating source on the motion of a test particle in the strong field regime. For this purpose the Hartle-Thorne metric, t…
Analytical determination of the two-body gravitational interaction potential at the 4th post-Newtonian approximation
Donato Bini, Thibault Damour
We complete the analytical determination, at the 4th post-Newtonian approximation, of the main radial potential describing the gravitational interaction of two bodies within the ef…
On the modification of the cosmic microwave background anisotropy spectrum from canonical quantum gravity
Donato Bini, Giampiero Esposito, Claus Kiefer +2
We evaluate the modifications to the cosmic microwave background anisotropy spectrum that result from a semiclassical expansion of the Wheeler-DeWitt equation. Recently, such an in…
