Long & Medium-Term Research: Inertial Confinement and the Auto-collimation of Jets This award is under the Long and Medium-Term Research at Foreign Centers of Excellence Program, which enables U.S. scientists and engineers to conduct three to twelve months of research abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award will support a four-month postdoctoral research visit by Dr. Adam Frank to the University of Leiden to work with Dr. Vincent Icke. The researchers will focus on a class of problems associated with the formation of astrophysical jets. Based on a study of bipolar outflow in Planetary Nebulae, Drs. Frank and Icke believe that a single mechanism associated with a single geometry is responsible for the ubiquitous, well collimated flows. They will use sophisticated numerical hydrodynamic code to simulate the interaction of aspherical stellar outflows and the production of jets. The goal of this project is to demonstrate the efficacy of this process over a wide range of length and time scales beginning with stars and ending with galaxies. They will then go further and provide "theoretical observations" allowing detailed comparisons of the models with what is seen in the telescope. The award recommendation provides funds to cover international travel and a stipend for four months plus a dependent allowance.
