“…Using ten orbits of Galileo data, Menietti et al [1998] were able to show significant correlation of Jovian radio emission with the satellite Ganymede. Subsequently Menietti et al [2001] found a significant correlation with the satellite Callisto.…”

[1] Jupiter decameter wavelength emissions (DAM) have a well-known correlation with the orbital phase of Io. Menietti et al. (1998Menietti et al. ( , 2001 showed that the Galileo spacecraft data show correlations with the orbital phase of Ganymede and Callisto. Using more Galileo data we study the influence of Europa using a unique occurrence probability data compilation technique that includes rotation period averaging and removal of Io influence. We also remove the known effects of Ganymede and Callisto. From occurrence probability graphs, we find a small but significant correlation between the 2.0-5.6 MHz band of the DAM emission and the orbital phase of Europa. Statistical tests show significance values much greater than the 99% confidence level (Z-test > 5s) for a Europa phase interval of 260°-290°. These analyses give further evidence for Alfvénic interactions between Europa and Jupiter.

“…Recent papers have shown that in addition to Io, the satellites Callisto, Ganymede, and Europa show a measurable influence on Jupiter's low‐frequency decametric radio emission [ Menietti et al , 1998, 2001; Higgins et al , 2006]. The influence of Io's orbital position on Jupiter's radio emission has long been known [ Bigg , 1964].…”

[1] Jupiter's satellite Io no longer has the only known effect in controlling the lowfrequency Jovian radio emissions. Menietti et al. (1998Menietti et al. ( , 2001) used a long and contiguous set of data in the range of 2.0-5.6 MHz from the Galileo spacecraft and found correlations with the orbital phase of Ganymede and Callisto. Recently, Higgins et al. (2006) used all of the Galileo orbiter data and found that Europa's phase shows a minor but statistically significant effect on the lower range of decametric emissions. In this paper, results are found that confirm previous work for all four Galilean satellites by combining Voyager 1 and Voyager 2 flyby data in the frequency range of 2.1-5.8 MHz. The data were analyzed using the unique occurrence probability data compilation technique that includes 10-hour averaging and satellite bias removal. A statistical significance Z-test was computed to compare sample populations for each enhanced region of occurrence against the background. We find significance values greater than the 95% confidence level (Z > 2s) for Io, Europa, Ganymede, and Callisto. Least squares fits to histograms of relative occurrence probability also show similar results. The cause of these correlations is believed to be Alfvénic interactions between the individual satellite and Jupiter.

“…Europa, Ganymede and Callisto also control jovian decametric radiation, although to a lesser degree than Io (Menietti et al 1998(Menietti et al , 2001, and Ganymede and Europa also cast auroral footprints. The unipolar inductor model is also applicable to systems where Jupiter is replaced by a magnetic white dwarf.…”

Abstract. Terrestrial planets in close orbits around magnetic white dwarf stars are potential electron-cyclotron maser sources, by analogy to planetary radio emissions generated from the electrodynamic interaction between Jupiter and the Galilean moons. We present predictions of radio flux densities and the number of detectable white-dwarf/terrestrial-planet systems, and discuss a scenario for their formation.
