Complementary astrometry of Cassini Imaging Science Subsystem images of Phoebe
Li, Y.; Cooper, N. J.; Lainey, V. +5 more
Phoebe is the only major satellite of Saturn with a retrograde orbit. The Cassini Imaging Science Subsystem (ISS) took a lot of Phoebe images between 2004 and 2017, but only a selection of them has been reduced. In this paper, we reduced the remaining ISS images of Phoebe. In the reduction, the Gaia EDR3 catalogue was used to provide the reference…
On the potential variation of charged dust in Saturn's magnetosphere: The dust-plasma interaction
Rehman, Umer; Hussain, Ibrar; Qammar, Ambreen
We presented a theory describing interaction between cold plasma and dust grain based on Cassini observations of Enceladus in Saturn's E ring. We assumed a finite-sized dust cloud with inside plasma to simulate the environment. The dust cloud that results from this scenario has a different potential than the surrounding plasma. Cassini's observati…
