Second Order Post Newtonian Equations of Light Propagation in Multiple Systems
Chongming Xu, Yanxiang Gong, Xuejun Wu +2
The first order post Newtonian scheme in multiple systems presented by Damour-Soffel-Xu is extended to the second order one for light propagation without changing the advantage of…
General-relativistic perturbation equations for the dynamics of elastic deformable astronomical bodies expanded in terms of generalized spherical harmonics
Chongming Xu, Xuejun Wu, Michael Soffel
In our previous paper, based on the Carter & Quintana framework and the Damour-Soffel-Xu scheme, we deduced a complete and closed set of post-Newtonian dynamical equations for elas…
General Formula for Comparison of Clock Rates -- Applications to Cosmos and Solar System
Chongming Xu, Xuejun Wu, Erwin Bruening
In this paper we deduce a quite general formula which allows the relation of clock rates at two different space time points to be discussed. In the case of a perturbed Robertson-Wa…
Post Newtonian Rigid Body
Chongming Xu, Jin-he Tao, Xuejun Wu
In this paper, it is the first time to construct a complete post-Newtonian (PN) model of a rigid body by means of a new constraint on the mass current density and mass density. In…
Relativistic theory of elastic deformable astronomical bodies: perturbation equations in rotating spherical coordinates and junction conditions
Chongming Xu, Xuejun Wu, Michael Soffel +1
In this paper, the dynamical equations and junction conditions at the interface between adjacent layers of different elastic properties for an elastic deformable astronomical body…
Extending the first-order post-Newtonian scheme in multiple systems to the second-order contributions to light propagation
Chong-ming Xu, Xue-jun Wu
In this paper, we extend the first-order post-Newtonian scheme in multiple systems presented by Damour-Soffel-Xu to the second-order contribution to light propagation without chang…
