Synchronization mechanism of sharp edges in rings of Saturn
We propose a new mechanism which explains the existence of enormously sharp edges in the rings of Saturn. This mechanism is based on the synchronization phenomenon due to which the epicycle rotational phases of particles in the ring, under certain conditions, become synchronized with the phase of external satellite, e.g. with the phase of Mimas in the case of the outer B ring edge. This synchro...
متن کاملSeeing the Shadow of Rings around a “Super Saturn”
Astronomers think they have found a planet that has a giant set of rings around it, over 200 times larger than the rings around the planet Saturn. The planet is young enough that moons may be forming out of the material of the rings, and we are seeing the shadows of the rings here on Earth. We are now looking for other planets that have giant rings around them, and we may see rings in 2017 arou...
متن کاملOptical Properties of Saturn ' S Rings : I . Transmission
All existing observational data relating to the transmission properties of Saturn's rings are discussed. Fromsuch data the optical thickness of the crape ring is determined as a function of its distance from the planet.Limiting values for ring B and a new value for the inner radius of ring B are established. The shape of thepressure curve of a gas cloud evidently associated with rin...
متن کاملThe Saturn rings origin: contribution of electromagnetism (to the unified theory of the origin of planetary rings)
Electromagnetic modeling and experimental data observation for Saturn’s rings points to the conjecture that the particles constituting the rings may be superconductive. We also argue that the rings could be originated from the protoplanetary cloud of particles if particles are superconducting. The rings system emerges some time after the magnetic field of the planet is being formed. For example...
متن کاملO2 from over the Main Rings into the Inner Magnetosphere of Saturn
The detection of a stable O2 atmosphere over Saturn’s main rings was one of the first major discoveries of the Cassini mission. The primary source of neutral O2 for this ring atmosphere was suggested to be due to solar UV photons that produce O2 by decomposition of H2O ice particles in the main rings. This process, as well as charged particle radiation, can also produce O2 from ice grains in th...
