General post-Minkowskian expansion of time transfer functions
Pierre Teyssandier, Christophe Le Poncin-Lafitte
Modeling most of the tests of general relativity requires to know the function relating light travel time to the coordinate time of reception and to the spatial coordinates of the…
Angular distances in metric theories
Pierre Teyssandier, Christophe Le Poncin-Lafitte
The general expression of the angular distance between two point sources as measured by an arbitrary observer is given. The modelling presented here is rigorous, covariant and vali…
World function and time transfer: general post-Minkowskian expansions
Christophe Le Poncin-Lafitte, Bernard Linet, Pierre Teyssandier
In suitably chosen domains of space-time, the world function may be a powerful tool for modelling the deflection of light and the time/frequency transfer. In this paper we work out…
Variation of the speed of light due to non-minimal coupling between electromagnetism and gravity
Pierre Teyssandier
We consider an Einstein-Maxwell action modified by the addition of three terms coupling the electromagnetic strength to the curvature tensor. The corresponding generalized Maxwell…
Superenergy tensors for a massive scalar field
P. Teyssandier
We define a general class of superenergy tensors of even rank 2(n+1) for a real massive scalar field propagating in Minkowski spacetime. In the case where n=1, we establish that th…
Scintillation in scalar-tensor theories of gravity
C. Bracco, P. Teyssandier
We study the scintillation produced by time-varying gravitational fields within scalar-tensor theories of gravity. The problem is treated in the geometrical optics approximation fo…
