• Titan's internal structure inferred from a coupled thermal-orbital model (2005, background): “Predictions of liquid water layers within large icy satellites (Lunine and Stevenson, 1987; Grasset and Sotin, 1996; Deschamps and Sotin, 2001; Spohn and Schubert, 2003), supported for Ganymede and Callisto by Galileo magnetic data (Khurana et al., 1998; Kivelson et al., 2002), appears to conflict w”
• Sulfur's impact on core evolution and magnetic field generation on Ganymede (2005, background): “, Crary and Bagenal, 1998] or the field is generated by convection in an electrically conducting fluid, likely a liquid portion of a metallic core [Schubert et al., 1996; Kivelson et al., 2002].”
• Tidal dissipation within large icy satellites: Applications to Europa and Titan (2005, background): “M netic data returned during the flybies of both Ganym and Callisto may also indicate a conductive layer, pro bly made of salted water, at a depth of a few hundred kilometers within these two satellites(Zimmer et al., 2000 Kivelson et al., 2002).”
• JUpiter ICy moons Explorer (JUICE): An ESA mission to orbit Ganymede and to characterise the Jupiter system (2013, background): “A unique characteristic of Ganymede is its intrinsic magnetic field generated in the satellite’s metallic core, and comparable to dynamo-activity in the Earth and Mercury (Kivelson et al., 2002).”
• Dipole moment scaling for convection-driven planetary dynamos (2005, positive): “Our scaling yields order of magnitude agreement with the dipole moments of Earth, Jupiter, Saturn, Uranus, Neptune, and Ganymede, and predicts a multipolar-type dynamo for Mercury.”
• Geophysical controls of chemical disequilibria in Europa (2016, background): “In the largest icy bodies—Titan, Ganymede, and Callisto—and in bodies with a very thick H2O upper layer such as Triton, high pressures prevent microfracture formation, so water-rock reactions in these objects require additional mechanisms to generate permeability, such as tectonics, pore fluid expan”
• The search for a subsurface ocean in Ganymede with Hubble Space Telescope observations of its auroral ovals (2015, background): “The time-averaged magnitude of Jupiter’s magnetospheric field at the radial distance of Ganymede’s orbit is around 100 nT [Kivelson et al., 2004].”
• Oceans in the icy Galilean satellites of Jupiter (2002, background): “The magnetic field data gathered during several close fly-bys of Ganymede have also been proposed to be in part due to induction in an ocean in this satellite as well (Kivelson et al., 2002).”
• Tidal heating in icy satellite oceans (2014, background): “Global subsurface oceans are thought to occur on at least Europa, Ganymede, Callisto, Titan and perhaps Enceladus (Khurana et al., 1998; Kivelson et al., 2002; Bills and Nimmo, 2011; Iess et al., 2012; Postberg et al., 2011); our focus in this paper is to examine tidal dissipation within such…”
