$J/\psi$ azimuthal anisotropy in Ru+Ru and Zr+Zr collisions at $\sqrt{s_{NN}} = 200$ GeV in STAR

Charm quark serves as an important hard probe for studying the properties of the Quark Gluon Plasma (QGP). Measurements of $J/\psi$ anisotropy flow is a powerful tool to understand the interaction between charm quark and the QGP. With the high-statistics 200 GeV Ru+Ru and Zr+Zr collision data collected by the STAR experiment, $J/\psi$ anisotropy flow are measured as a function of $p_{T}$ and centrality. The non-flow contributions are highly suppressed by using the Event Plane Detector. The comparison to model calculations, as well as previous experimental results at RHIC and LHC will be discussed.
