Charm quarks are produced at very early stage of ultra-relativistic Au+Au collisions at RHIC top energy. This makes them an ideal probe of the Quark-Gluon Plasma, as they experience the whole evolution of the hot and dense medium. At STAR, production of charm quarks can be accessed via a direct topological reconstruction of hadronic decays of open charm hadrons, utilizing the excellent resolution of the Heavy Flavor Tracker.
