These objects include the toroidal halo interior of the main one and the two gossamer ones.
When the entities that compose these objects enter their planet's shadow, photoelectric processes shut down and those entities become more negatively charged. That results in a coupled oscillation between those entities orbital eccentricity and their semimajor axis, which is known as shadow resonance and explains the Thebe extension to one of these objects. A significant decrease in the brightness of one of these objects is known as the Metis notch. These objects include the toroidal halo interior of the main one and the two gossamer ones. They straddle the orbits of Amalthea and the other three inner moons of the planet that was hit by the Shoemaker-Levy 9 comet. For 10 points, name these features of the largest planet in our solar system, discovered by Voyager I and studied extensively by the Galileo mission.
