Zusammenfassung der Projektergebnisse

In course of the DFG-funded Project Martin Seiß developed a non-harmonic and non-linear model describing the propeller wakes including dissipative wake-damping processes. Using this, he managed to explain the dynamical variability and non-harmonic shape of these waves; and to further constrain the masses of the A ring moons Pan and Daphnis as well as their orbital eccentricities. Furthermore, he contributed essentially to the development of a three-dimensional propeller model used to explain the propeller shadows observed by Cassini during Saturn’s equinox in August 2009. The latter results of the shadow-casting propellers has been elected (by Cassini-scientists council) as a so-called Science Nugget at the occasion of the Cassini-Science Spring Meeting (PSG-meeting) at Jet Propulsion Institute/NASA in Pasadena in Feb. 2013.
