Query: Molecular picture for the $X_0(2866)$ as a $D^* \bar{K}^*$ $J^P=0^+$
  state and related $1^+,2^+$ states   We recall the predictions made ten years ago about a bound state of $J^P=0^+$
in $I=0 $ of the $D^* \bar{K}^*$ system, which is manifestly exotic, and we
associate it to the $X_0(2866)$ state reported in the recent LHCb experiment.
Fine tuning the parameters to reproduce exactly the mass and width of the
$X_0(2866)$ state, we report two more states stemming from the same
interaction, one with $1^+$ and the other with $2^+$. For reasons of parity,
the $1^+$ state cannot be observed in $D\bar{K}$ decay, and we suggest to
observe it in the $D^*\bar{K}$ spectrum. On the other hand, the $2^+$ state can
be observed in $D \bar{K}$ decay but the present experiment has too small
statistics in the region of its mass to make any claim. We note that
measurements of the $D^*\bar{K}$ spectrum and of the $D \bar{K}$ with more
statistics should bring important information concerning the nature of the
$X_0(2866)$ and related ones that could be observed.
