Description

In this paper we calculate the emission of gravity waves by the binary pulsar in the framework of five-dimensional spacetime. We consider spacetimes with one compact extra dimension. We show that the presence of additional degrees of freedom, especially the 'gravi-scalar', leads to a modification of Einstein's quadrupole formula. We compute the induced change for the binary pulsar PSR 1913 + 16 in the simple example of a 5D Minkowski background. In the example of a cylindrical braneworld it amounts to about 20% which is by far excluded by present experimental data
