Layered convection as the origin of Saturn’s luminosity anomaly
Saturn is brighter than expected for a gas giant of its age. Calculations of Saturn’s thermal evolution show that the presence of layered convection in Saturn’s interior—much like that observed in the Earth’s oceans—would have slowed the planet’s cooling and may explain Saturn’s anomalous luminosity.
