### Description

Heavy quarks are predominantly produced at early stages of high-energy heavy-ion collisions due to their large masses. Studies of interactions between heavy quarks and the Quark-Gluon Plasma (QGP) in different collision systems can provide new insights to the properties of the QGP. Thus measurements of heavy quark production via measuring the electrons from semi-leptonic decays of heavy flavor hadrons, also known as Non-Photonic Electron (NPE), in Au+Au collisions are crucial.
In this poster, we will present the latest measurements of the nuclear modification factor (R_{AA}) for NPE production in Au+Au collisions at √s_{NN} = 200 GeV from the STAR
experiment. We will also discuss the first result on separating NPE production between open charm and bottom hadron decays via the impact parameter method utilizing the Heavy Flavor Tracker.
