How do scalar-field dark matter haloes react to orbiting bodies?
  Low-energy, self-gravitating solutions of a scalar field coupled to gravity,
described by the Schrodinger-Poisson system, are good candidates for realistic
astrophysical structures, being particularly suited to describe dark matter
halos. In this work we study the scenario in which one of these structures is
gravitationally perturbed by a point-like mass. We analyse the effects that the
body has on the distribution of the scalar field and how it backreacts on the
body's motion. We show that an initially static, spherical structure can
develop rotating non-spherical clumps, the amplitude and the velocity of which
are directly related to the mass of the orbiting particle. We also study the
dissipation mechanisms involved in the transit of the point-like particle
across the scalar field structure and we observe that the force responsible for
the dissipation scales as the square of the mass of the particle.
