The velocity of gravitational waves

We examine the propagation of gravitational waves in the new field theory o f gravitation recently proposed by Novello-De Lorenci-Luciane (NDL). This e xamination is done on a solvable case corresponding to a spherically symmet ric static configuration. We show that in NDL theory the velocity of gravit ational waves is lower than light velocity. We point out some consequences of this result and suggest a possible scenario for its verification.
