Abstract: | Static spherically symmetric solutions of 4d Brans–Dicke theory include a set of naked singularity solutions. Dilatonic effects
near the naked singularities result in either a shielding or an antishielding effect from intruding massive test particles.
One result is that for a portion of the solution parameter space, no communication between the singularity and a distant observer
is possible via massive particle exchanges. Kaluza–Klein gravity is considered as a special case. |
