Description
Particle physics models of dark matter, and extensions to the Standard Model, predict the existence of a large abundance of light scalar degrees of freedom in the universe. From a diffuse cloud, these can form into clumps of energy - boson stars. Additionally, due to their high compactness, close to that of black holes, these solutions serve as test beds to study the non-linear dynamics of a large class of ultra-compact objects. We outline a method to obtain constraint satisfying binary Boson star initial data, and discuss the dynamics of merging binaries, focusing specifically on the formation of rotating Boson star remnants.
