This work is about Gaia BH3, a binary system formed by a 0.76 M⊙ star orbiting a 32.7 M⊙ black hole. The work focuses on evaluate the possibility of having a inner binary system of black holes instead of a single black hole. It has been performed through analytical analysis. We obtained that it cannot be ruled out this possibility and that, if it host a binary system of black holes, we would not be able to detect it with a probability greater than 77%, for coplanar orbits. The method developed in this work may apply to other systems and be thus useful for future discoveries
