摘要
In the context of the Randall-Sundrum braneworld, the minimal geometric deformation approach is used to generate a new physically acceptable interior solution to Einstein's field equations for a spherically symmetric compact distribution. This new solution is used to elucidate the role of exterior Weyl stresses from bulk gravitons on compact stellar distributions. We found strong evidences showing that the exterior dark radiation U+ always increases both the pressure and the compactness of stellar structures, and that the exterior 'dark pressure' P+ always reduces them.
