  In this work, we study systems composed of a $\rho/\omega$ and $B^*$ meson
pair. We find three bound states in isospin, spin-parity channels $(1/2, 0^+)$,
$(1/2, 1^+)$ and $(1/2, 2^+)$. The state with $J=2$ can be a good candidate for
the $B_2^*(5747)$. We also study the $\rho B$ system, and a bound state with
mass $5728$ MeV and width around $20$ MeV is obtained, which can be identified
with the $B_1(5721)$ resonance. In the case of $I=3/2$, one obtains repulsion
and thus, no exotic (molecular) mesons in this sector are generated in the
approach.
