Professor Emeritus William M. Irvine has been elected to the Steering Committee of the new IAU Division F, Planetary Systems and Bioastronomy. Commission F "deals with our Solar System, extrasolar planetary systems, and bioastronomy. To this purpose, the Division promotes studies concerning planetary systems, including our own, aimed at the understanding of their formation and evolution, from the point of view of the dynamics and of the physics, as well as of the occurrence of conditions favourable to the development of life in the universe. Division F promotes the dissemination of reliable physical and dynamical data concerning the astronomical objects in the above fields, and oversees the assignment of proper nomenclature and discovery credits, where appropriate."
Some 1740 of the IAU's >10,000 members belong to Division F.
