  In this talk I present a study of the $D^* \rho$ system made by using the
method of QCD sum rules. Considering isospin and spin projectors, we
investigate the different configurations and obtain three $D^*$ mesons with
isospin $I=1/2$, spin $S=0$, $1$, $2$ and with masses $2500\pm 67$ MeV,
$2523\pm60$ MeV, and $2439\pm119$ MeV, respectively. The last state can be
related to $D^*_2(2460)$ (spin 2) listed by the Particle Data Group, while one
of the first two might be associated with $D^*(2640)$, whose spin-parity is
unknown. In the case of $I=3/2$ we also find evidences of three states with
spin 0, 1 and 2, respectively, with masses $2467\pm82$ MeV, $2420\pm128$ MeV,
and $2550\pm56$ MeV.
