$\Upsilon$ production in STAR

The production of heavy quarkonia states in p+p, p+A and A+A collisions provide an important tool to study the properties of Quark-Gluon Plasma. Their suppression pattern can be used as a thermometer to the QCD matter and henceforth the study of $\Upsilon$ production is of paramount importance. With the completion of the STAR Electromagnetic Calorimeter and with the increased luminosity provided by RHIC in Run 6 and 7, the study of $\Upsilon$ production via the di-electron channel becomes possible. We present the results on $\Upsilon$ measurements in p+p collisions (from Run 6) along with the preliminary results from Au+Au collisions (in Run 7) at $\sqrt{s_{\rm{NN}}} = 200$ GeV from the STAR experiment.
