  In this paper, we study the dissociation of heavy quarkonium in the spinning
black hole background. Specifically, we analyze the spectral function of
charmonium and bottomonium in the spinning black hole background and examine
how the angular momentum affects the dissociation of $J/\Psi$ and
$\Upsilon(1S)$. From the results, we find that the angular momentum decreases
the peak height and expands the peak width of the spectral function which
indicates it enhances the dissociation of heavy vector mesons. Moreover, the
angular momentum has a stronger dissociation effect in the transverse
orientation, revealing the directional influence of angular momentum.
