Title : The origin of Saturn's visible dense rings, first observed by Galileo in 1610 and confirmed by Cassini observations in 2004-2017
Abstract:
Here we present for the first time a new explanation for the origin of Saturn's visible dense rings. Space is not empty; it is fill with gravity and magnetism. Italian scientist G. Galileo discovered the visible dense rings in 1610. For 400 years now, their origin, dynamics, evolution and age have remained a mystery. British scientist J.K. Maxwell proved in 1856 that the visible dense rings along the orbits consist of an infinite number of separated chunks. NASA has flown three missions to explore the Saturn system: Pioneer-11, Voyager-1, Voyager-2, and collaborated with the Italian Space Agency on the outstanding Cassini mission, 2004-2017. However, there is no yet answer. After Cassini's grand finale in 2017, there is no final consensus on the origin and age of the visible dense rings.
We show that Saturn's magnetism makes an important contribution to the origin of visible dense rings, and helps to explain some of their observed features, for example, such as the equilibrium separation of ice chunks in dense rings, which has not explained yet, and others. Many features of dense rings were observed and measured by the Cassini probe, but could not be explained within the framework of known gravitational theories. There are number of gravitational models of the origin of Saturn rings: a moon of the planet could have been disrupted by a passing celestial body; the rings could have been generated by the chunks separated from icy moons of the outer planets by collision with comets or meteorites; the ring chunks can be debris of a large comet tidally broken by the planet; the rings can be the relic of a protosatellite disk. Unfortunately, no theory has provided a convincing explanation for the observed features and peculiarities of Saturn's visible dense rings among the bodies of the Solar System. Cassini measured that the chunks of rings mostly consist of 90-95% of water ice. In addition, Cassini found the ratio of deuterium and hydrogen isotopes for the ice of Saturn’s visible dense rings is the same as for the Earth’s ice. This fact indicates the similarity of ice in the rings and Earth’s ice. The science of ice is complicated. About 20 types of ice known on Earth. Ice XI is more suitable for Saturn's dense rings. It has stable parameters below 73K and it is diamagnetic. With these data, we have found a solution to the problem of the interaction of gravitational field and magnetic field of Saturn with diamagnetic ice chunks moving in Kepler’s orbits around Saturn in a protoplanetary cloud. An interesting fact is that accounts the action of magnetic field of Saturn in addition to the action of gravitational field explains the transformation of a protoplanetary cloud filled with the ice chunks into a disk of stable visible dense rings system as well as it accounts for a strong planar structure of rings located at the magnetic equator of Saturn. Cassini probe discovered that Saturn's magnetic equator almost coincides with the geographical one. Saturn's magnetic field has a dominating dipolar structure in the region of visible dense rings. Finally we are coming to conclusion that Saturn could create its dense rings from the ice chunks of the protoplanetary cloud with the help its own magnetic field due to the action of an additional third force of diamagnetic expulsion and the mechanism of magnetic anisotropic accretion. An interesting feature is that under the influence of the planet's magnetic field, the ice chunks of dense rings remain separated; otherwise, if they will stick together because of their own gravity, they can form another satellite. J.C. Maxwell has proved that rings along the orbit are not continuous, but consist of separated chunks of matter [1859. MNRAS, 19: 297]. Unfortunately, at his time, there was no knowledge that rings consist of ice and this ice is diamagnetic. It becomes to be clear only after measurements of rings by the Cassini probe. The Newtonian dynamics for a single ice chunks differs from the dynamics for ice chunks assembled in the rings system. Chunks repel each other under the influence of magnetic force and are attracted to each other under the influence of gravity. From the balance of the forces of gravitational attraction and magnetic repulsion, we have derived the expression for the calculation of equilibrium and stable distance between the ice chunks in the rings.
The origin and observed features of the visible dense rings such as their thin structure in the group of them and equilibrium separations of chunks, all of them we received for the first time for 400 years after Galilei saw rings in 1610. All presented results confirmed by the measured data and by the imaging of the Saturn’s visible dense rings obtained by the Cassini probe in 2004-2017.
