Abstract

We study the partial time dependent collapse of a spherically symmetric compact object with initial mass M₁+M₂ and final mass M₂ and the waves of space-time emitted during the collapse via back-reaction effects. We obtain exact analytical solutions for the waves of space-time in an example in which M₁=M₂=(M₁+M₂)/2. The wavelengths of the space-time emitted waves during the collapse have the cut (we use natural units c=ℏ=1): λ< (2/b), (1/b)-being the time scale that describes the decay of the compact object.
