Abstract

Because of the attraction of gravity a real Klein-Gordon field can form long living spherically symmetric localized objects, called oscillatons. These configurations are so long living that until recently by all numerical methods they appeared to be exactly time-periodic. In this report we compare the small-amplitude analytic results for the mass loss rate of oscillatons with the numerical results obtained by the solution of the Fourier mode equations.
