Overview of open heavy flavor measurements in STAR

We present an overview of measurements related to open heavy flavor production. Results from indirect reconstruction of heavy flavor via semi-leptonic decays in p + p and minimum bias Au+Au collisions at = 200 GeV, and results from D meson measurements via their hadronic decay channel in minimum bias Cu+Cu and Au+Au collisions are discussed. For the semi-leptonic decays the focus is on partonic energy loss, RAA, and the use of e-h and e-D0 azimuthal correlation measurements to extract the B meson contribution to the non-photonic electron spectrum. For the hadronic decay the focus is on open charm yields in Cu+Cu collisions and first measurements of D meson in heavy ion collisions using a secondary vertexing technique.
