Abstract

This paper is dedicated to investigate an astrophysical method to obtain the new dynamics generated by extra dimensions as well as bounds for the brane tension. Using the modified Einstein equations in the brane with a vanishing non-local effects, we study the contributions of the modified radiated power by gravitational waves and the stellar period modified by branes in a binary system composed by two neutron stars. Finally we propose two lower energy bounds, using these astrophysical methods.

Keywords: Branes; extra dimensions.

35. In general ξ_μv ≠ 0 in realistic astrophysical models, however it is necessary to note that the system of equations for the exterior is not closed until a further condition is given on the Weyl tensor; for this reason ξ_μv ≠ 0 [16].
