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 spi","authors_text":"A. Martinez Torres, E. Oset, F. S. Navarra, K. P. Khemchandani, M.
