Nominator's project description

Professor Wolszczan is an astronomer of international standing, best known for the discovery of planets around a millisecond pulsar. The many astronomical groups searching for extra-terrestial planets were astounded when Professor Wolszczan showed that there were two, possibly more planets around the pulsar PSR1257+12. The planets were discovered through the use of accurate timing of the period of the pulsar and attributing the residues in the timing solution to rotating planets around the object. Professor Wolszczan was educated at the Torun University, Poland. During his PhD studies on pulsars he has spent considerable time at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn. This cooperation has continued up to this day. Professor Wolszczan is now a Distinguished Professor at the Astronomy Department of Penn State University, USA. He is going to cooperate with astronomers in Germany in the analysis of an extended data base of pulsar timing observations that have been collected at his initiative with the Effelsberg 100m radio telescope near Bonn.
