Binary Darboux Transformations in Bidifferential Calculus and Integrable Reductions of Vacuum Einstein Equations

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
We present a general solution-generating result within the bidifferential calculus approach to integrable partial differential and difference equations, based on a binary Darboux-type transformation.

Detection of rapid orbital expansion of Saturn’s moon Titan [PDF]

open access: yes, 2019
The Saturn satellite system is a complex dynamical system with several gravitational interactions happening between the satellites, the rings and the central body, such as resonances, librations and tides.

The Vertical Structure of the F Ring of Saturn from Ring-Plane Crossings

open access: yes, 2013
We present a photometric model of the rings of Saturn which includes the main rings and an F ring, inclined to the main rings, with a Gaussian vertical profile of optical depth.

The brightening of Saturn’s F ring [PDF]

open access: yesIcarus, 2012
Image photometry reveals that the F ring is approximately twice as bright during the Cassini tour as it was during the Voyager flybys of 1980 and 1981. It is also three times as wide and has a higher integrated optical depth. We have performed photometric measurements of more than 4,800 images of Saturn's F ring taken over a five-year period with ...

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

The theory of Saturn's rings [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1935
In his Adams Prize Essay for the year 1856 J. CLERK MAXWELL* took the first step towards a comprehensive theory of the unique system of rings associated with Saturn. The main theme of MAXWELLs work was to devise a model for the system of rings which could move in a steady state of motion round Saturn and which could be stable for small disturbances ...

Synchronicity in Post‐Jungian Astrology: A Cosmological Quest

open access: yesJournal of Analytical Psychology, Volume 70, Issue 5, Page 808-824, November 2025.
Abstract Jung promoted the idea of synchronicity in 1928, in the context of discussing the Chinese way of thinking. From 1928 to 1951, Jung’s informal formulations led to more than one understanding of synchronicity. He even tried to apply synchronicity to an astrological experiment.

The E-ring of Saturn

open access: yesInternational Astronomical Union Colloquium, 1981
AbstractThe origin of the E-ring of Saturn and its relationship to Enceladus is a well known problem. Rather than assuming that the ring was formed as a result of one big impact long ago or that it is a consequence of ejection of subcrustal water by tidally induced stresses and cracks of the satellite, it is proposed that the ring is formed as a ...
