Abstract

Analyzing a database of 26 years of observations of Jupiter from the Nan¸cay Decameter Array, we study the occurrence of Io–independent emissions as a function of the orbital phase of the other Galilean satellites and Amalthea. We identify unambiguously the emissions induced by Ganymede and characterize their intervals of occurrence in CML and Ganymede phase and longitude. We also find hints of emissions induced by Europa and, surprisingly, by Amalthea. The signature of Callisto–induced emissions is more tenuous.
