Cassini Ring Seismology as a Probe of Saturn's Interior I: Rigid Rotation [PDF]
, 2018 Seismology of the gas giants holds the potential to resolve long-standing questions about their internal structure and rotation state. We construct a family of Saturn interior models constrained by the gravity field and compute their adiabatic mode eigenfrequencies and corresponding Lindblad and vertical resonances in Saturn's C ring, where more than ...

Stellar Physics and General Relativity
Astronomische Nachrichten, EarlyView.ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...

How Saturn could create rings by itself. The third force of diamagnetic expulsion and the mechanism of the magnetic anisotropic accretion of the origin of Saturn's rings [PDF]
arXiv, 2021 Here we demonstrate how Saturn could create its rings by itself, with the additional action of its axisymmetric magnetic field once appeared. A new mechanism for the origin of Saturn's rings is proposed for the first time. It includes the appearance of an additional third force - the force of diamagnetic expulsion of a diamagnetic ice particle after ...

TiNiSi‐Type ALiAu (A = Ca, Sr, Ba, Eu, Yb) Compounds: Alternative Use of “Excess” Electrons
Chemistry – A European Journal, EarlyView.Excess electrons distinguish the bonding in ALiAu (A = Yb, Ca, Eu, Sr, Ba), a new series of intermetallic compounds crystallizing in TiNiSi type. According to bonding analysis, these metallic phases are classified as aurides containing polycations with multiatomic bonding between A, Li, and Au . Abstract New TiNiSi‐type compounds ALiAu (A = Ca, Sr, Ba,

European Journal of Inorganic Chemistry, Accepted Article.The introduction of alkyl chains into Ru(II) polypyridyl complexes is important for synthesizing functional Ru‐based materials. Generally, alkyl chains are introduced by organic synthesis. Herein, we developed a synthesis method involving photoacid generation to produce ether‐substituted Ru(II) polypyridyl complexes.

Wandering Among Models: Stendhal, Proust, Sebald
Acta ad Archaeologiam et Artium Historiam Pertinentia, 2017 This paper draws on twofold fictional landscapes; the imaginary landscapes emerging in the writings of Stendhal, Marcel Proust and W.G. Sebald as well as the invented landscapes evoked by the architectural model.

A recent origin for Saturn's rings from the collisional disruption of an icy moon [PDF]
, 2017 The disruption of an icy moon in a collision with an interloping comet a few hundred million years ago is a simple way to create Saturn's rings. A ring parent moon with a mass comparable to Mimas could be trapped in mean motion resonance with Enceladus and Dione in an orbit near the current outer edge of the rings just beyond the Roche zone.

A diffuse core in Saturn revealed by ring seismology [PDF]
arXiv, 2021 The best constraints on the internal structures of giant planets have historically come from measurements of their gravity fields. These gravity data are inherently mostly sensitive to a planet's outer regions, providing only loose constraints on the deep interiors of Jupiter and Saturn.

The production of terra sigillata in Arezzo, Central Italy: an archaeometric investigation
Archaeometry, EarlyView.Abstract This work deals with the archaeometric investigation on 25 fragments of terra sigillata (red‐coated ceramic ware and moulds) found in the city of Arezzo, Tuscany (central Italy), and attributed to several important workshops from the first century BCE to the second century CE.
