Rough Estimates of Solar System Gravitomagnetic Effects in Post-Newtonian Gravity

open access: yesUniverse
In order to properly describe the gravity interactions, including the mass currents, in gravitomagnetism, we construct four Maxwell-type gravitational equations that are shown to be analogs of the Maxwell equations in electromagnetism.

Filling Voids: Cubic Carbodiimide Nitride Nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 17, November 25, 2025.
The crystal structures of (Ba6Nx)2[MN4][CN2]6 (left) and “ideal” 2 × 2 × 2 Perovskite (right) show similar linkage patterns despite differently shaped coordination polyhedra. Cubic carbodiimide nitride nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W are synthesized by various high‐temperature reactions and their respective crystal

Saturn [PDF]

open access: yes
This lithograph shows images of Saturn, its rings, and four of its moons. The images were captured by the Voyager 1 and 2 spacecraft. They are accompanied by a brief description and history, some statistical facts, and important dates in the exploration ...

Ring particle sizes and composition derived from eclipse cooling curves and reflection spectra [PDF]

open access: yes
The probable chemistry of the Saturn rings is reviewed. Reflectance spectra for H20 and NH3 frosts and Saturn's rings are compared, along with temperature dependence of 1.6 microns water frost feature.

The theory of the divisions in Saturn's rings [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1941
In an earlier paper on this subject the author (1921) proposed a theory of the rings which showed satisfactory agreement with the observed measurements of the rings. The mathematical method was, however, subjected to criticism. In the present paper the subject is again attacked by an entirely different method which is free from the objections raised ...

Planetary ring studies [PDF]

open access: yes
The following topics are covered: (1) characterization of the fine scale structure in Saturn's A and B rings; (2) ballistic transport modeling and evolution of fine ring structure; (3) faint features in the rings of Saturn; (4) the Encke moonlet; (5 ...

The Saturn System [Book Review] [PDF]

open access: yes, 1979
A book about the Saturn system which predates the imminent discoveries of Pioneer 11 and Voyager would seem to be premature. However, this compendium of review papers on Saturn, its satellites, its rings, and its magnetosphere is the most ...

The Mariner Jupiter/Saturn photopolarimeter experiment [PDF]

open access: yes
Observations of Saturn's rings by the Mariner Jupiter/Saturn photopolarimeter are studied. From these observations attempts were made to: (1) determine the size, shape, albedo, distribution, and orientation of particles in the rings, (2) measure ...
