Descripción
Dark matter capture by celestial objects is widely studied as one of the methods to indirectly detect dark matter. Celestial objects, such as neutron stars, brown dwarfs, and planets, first gravitationally attract ambient dark matter particles. If dark matter particles are heavy enough, they transfer energy to those objects upon scattering, being gravitationally bound. This process ends up accumulating a large number of dark matter particles inside celestial bodies, producing a detectable signature including the decay products of their annihilation. In this talk, we will examine the underlying assumptions in this scenario and point out that they might be inconsistent with each other in some cases.
