Compact body interactions and boson stars

ORAL

Abstract

The two body problem in General Relativity is studied in this work by solving numerically Einstein Equations. The approach chosen consists of modeling (at least) one of the compact object by means of a boson star, which is a self-graviting configuration of (complex) scalar field. We present studies of binary systems involving one of these boson stars with another companion compact object. The results illustrate rich phenomenology with interest consequences on the radiated gravitational waves.
