In the peculiar A-type star 73 Draconis the heavy elements Osmium (Z = 76), Platinum (78) , Gold (79) and Uranium (92) were identified. Furthermore a large number of molecular bands due to CN and to a lesser degree to CH, were detected. This star is the first one up to now in which both anomalies were detected. The complete paper will be published elsewhere.Asociación Argentina de Astronomí
