Motion of extended fluid bodies in the Newtonian limit of gravity
Bofeng Wu, Xiao Zhang
In the Newtonian limit of gravity, for an isolated self-gravitating system consisting of extended fluid bodies, the inter-body dynamics are studied by applying the symme…
Black hole images under spherical-shell and circular-annulus accretion models in Schwarzschild spacetime: a semianalytical approach
Bofeng Wu, En-Wei Liang, Xiao Zhang
In the static and infalling spherical-shell models of optically thin accretion on Schwarzschild black hole, the formulas for the integrated intensities observed by a distant observ…
Multipole expansion of the gravitational field in a general class of fourth-order theories of gravity and the application in gyroscopic precession
Bofeng Wu, En-Wei Liang
A viable weak-field and slow-motion approximation method is constructed in gravity, a general class of fourth-order theories of gravity. By ap…
