We study composite systems of light ({rho} and {omega}) and heavy (D*) vector mesons by using the interaction within the hidden gauge formalism. We find a strong attraction in the isospin, spin channels (I,S)=(1/2,0), (1/2,1), and (1/2,2) with positive parity. The attraction is large enough to strongly bind these mesons in states with these quantum numbers, leading to states which can be identified with D{sub 2}*(2460) and probably with D*(2640), the last one without experimental spin and parity assignment. In the case of I=3/2, one obtains repulsion and thus, no exotic mesons in this sector are generated in the approach.
