Dr. Stuart J. Weidenschilling, Senior Scientist, conducts theoretical research on the origin of the solar system, particularly the aerodynamic interactions of solid bodies and gas in the primordial solar nebula, and the formation of planetesimals. He also conducts numerical simulations of the accretion of planetesimals into planets, using a unique multi-zone computer code, which has recently been converted to run on parallel processors. Drs. Weidenschilling and Davis are using this code to investigate the formation and thermal histories of asteroids, the evolution of comets in the Kuiper belt, the formation of Jupiter, and other problems of cosmogony. In collaboration with Dr. Francesco Marzari (Universita di Padova, Italy), Dr. Weidenschilling is also studying the formation of extra-solar planets. He has served on the editorial board of Icarus, the international journal of planetary science, and on several NASA review panels. He is a fellow of the American Geophysical Union, and asteroid 3639 Weidenschilling is named for him.
