- In this work we investigate the possible emergence of Efimov states in the $D^*D^*D^*$ system with $J^P=0^-$ and isospin $I=\tfrac{1}{2}$, assuming the existence of the heavy partner of the $T_{cc}^+$, dubbed $T_{cc}^*$, near the $D^*D^*$ threshold as predicted by Heavy-Quark Spin Symmetry. We find that $(I)J^P=(\frac{1}{2})0^-$ three-body bound states can be formed, with properties that suggest that the Efimov effect can be realised for reasonable values of the molecular probability and binding energy of the $T_{cc}^*$.
