Revisiting the analogue of the Jebsen-Birkhoff theorem in Brans-Dicke gravity (1801.00804v2)
Published 2 Jan 2018 in gr-qc
Abstract: We report the explicit form of the general static, spherically symmetric, and asymptotically flat solution of vacuum Brans-Dicke gravity in the Jordan frame, assuming that the Brans-Dicke scalar field has no singularities or zeros (except possibly for a central singularity). This general solution is conformal to the Fisher-Wyman geometry of Einstein theory and its nature depends on a scalar charge parameter. Apart from the Schwarzschild black hole, only wormhole throats and central naked singularities are possible
