Overview of open heavy-flavor production from STAR

We report the results on the open heavy-flavor production measured by the STAR experiment in Au+Au collisions at a center-of-mass energy per nucleon-nucleon pair of 200 GeV at RHIC, including the nuclear modification factors for $D^0$, $D^{\pm}$, electrons from $B$ and $D$ hadron decays, and non-prompt $J/\psi$ and $D^0$. We also present results on elliptic and triangular anisotropic flows for $D^0$ as well as the production ratios of $D^{\pm}_s/D^0$ and $\Lambda_c/D^0$. These results are compared to various theroretical predictions, providing us valuable information on the properties of the quark-gluon plasma.
