Abstract

According to numerical simulations, general relativistic massive real scalar fields can form extremely long living oscillating localized objects, called oscillating soliton stars or oscillatons. We present a small-amplitude expansion to describe the core region of these configurations. To leading order we obtain the Schrodinger-Newton equations. However, the small-amplitude expansion is only an asymptotic one, and consequently misses a nonperturbatively small oscillating tail which is responsible for a tiny energy loss of oscillatons, making them non-exactly periodic. The energy loss rate is calculated by complex extension of the Fourier mode equations and applying Borel summation.
