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…
Multipole analysis on stationary massive vector and symmetric tensor fields
Bofeng Wu
The multipole expansions for massive vector and symmetric tensor fields in the region outside spatially compact stationary sources are obtained by using the symmetric and trace-fre…
The gravitational field outside a spatially compact stationary source in a generic fourth-order theory of gravity
Bofeng Wu, Chao-Guang Huang
By applying the symmetric and trace-free formalism in terms of the irreducible Cartesian tensors, the metric for the external gravitational field of a spatially compact stationary…
A signature invariant geometric algebra framework for spacetime physics and its applications in relativistic dynamics of a massive particle and gyroscopic precession
Bofeng Wu
A signature invariant geometric algebra framework for spacetime physics is formulated. By following the original idea of David Hestenes in the spacetime algebra of signature $(+,-,…
