Saturn Ring Seismology: Evidence for Stable Stratification in the Deep Interior of Saturn [PDF]
2014, Icarus, 242, 283-296, 2014 Seismology allows for direct observational constraints on the interior structures of stars and planets. Recent observations of Saturn's ring system have revealed the presence of density waves within the rings excited by oscillation modes within Saturn, allowing for precise measurements of a limited set of the planet's mode frequencies.

Remnant for all black objects due to gravity's rainbow
Nuclear Physics B, 2015 We argue that a remnant is formed for all black objects in gravity's rainbow. This will be based on the observation that a remnant depends critically on the structure of the rainbow functions, and this dependence is a model independent phenomena. We thus

Charged Grains In Saturn's F-Ring: Interaction With Saturn's Magnetic Field [PDF]
, 2003 Saturn's dynamic F-Ring still presents a challenge for understanding and explaining the kinematic processes that lead to the changing structure visible in our observations of this ring. This study examines the effect of Saturn's magnetic field on the dynamics of micron-sized grains that may become electrically charged due to interaction with plasma in ...

The Vertical Structure of the F Ring of Saturn from Ring-Plane Crossings [PDF]
2013 Icarus, Volume 226, Issue 2, p. 1275-1293, 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. This model reproduces the asymmetry in brightness between the east and west ansae of the rings of Saturn that was observed by the Hubble Space Telescope (HST) within a few ...

Mapping out Patience: Cartography, Cinema and W.G. Sebald
Humanities, 2015 Cinematic cartography can be an especially powerful tool for deep mapping, as it can convey the narratives, emotions, memories and histories, as well as the locations and geography that are associated with a place. This is evident in the documentary film

Saturn's Seismic Rotation Revisited [PDF]
arXiv, 2023 Normal mode seismology is a promising means of measuring rotation in gas giant interiors, and ring seismology presents a singular opportunity to do so at Saturn. We calculate Saturn's normal modes of oscillation and zonal gravity field, using nonperturbative methods for normal modes in the rigidly rotating approximation, and perturbative methods for ...

Metastable Black Saturns [PDF]
JHEP 0809:003,2008, 2008 Black Saturns have multiple horizons and so offer a testing ground for the ideas of black hole thermodynamics. In this note, we numerically scan for phases that are in equilibrium by extremizing total entropy in the 2-dimensional moduli space of stationary, singly rotating black Saturns with fixed total mass and angular momentum.

Plaire, instruire et émouvoir : le rôle du lecteur dans la définition de la visée de l’œuvre d’art
Signata, 2019 This paper deals with the kinds of works of art — in this case Rembrandt’s famous “Anatomy Lesson of Dr. Nicolaes Tulp” — that link the esthetic function to the documentary function.

High‐Performance Polymer‐derived Ceramics in LCD 3D Printing
Advanced Science, EarlyView.This study highlights the potential of silicon oxycarbide‐based formulations for producing polymer‐derived ceramics with superior properties via LCD 3D printing. VMM‐based ceramics demonstrate a remarkable 50‐fold increase in compressive strength (up to 17 MPa) compared to SPR‐684, along with exceptional high‐temperature survivability (up to 1500 °C ...

Spring and Power in Hovering Ornithopters
Advanced Intelligent Systems, EarlyView.Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...
