Analysing the new Saturnian rings, R/2004 S1 and R/2004 S2
(Springer, 2005-12-01)
The Cassini-Huygens arrival into the Saturnian system brought a large amount of data about the satellites and rings. Two diffuse rings were found in the region between the A ring and Prometheus. R/2004 S1 is coorbital to ...
The brightening of Saturn's F ring
(Academic Press Inc. Elsevier B.V., 2012-05-01)
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 ...
Some comments on the F ring-Prometheus-Pandora environment
(Elsevier B.V., 2004-01-01)
The system formed by the F ring and two close satellites, Prometheus and Pandora, has been analysed since the time that Voyager visited the planet Saturn. During the ring plane crossing in 1995 the satellites were found ...
Aggregates in the strength and gravity regime: Particles sizes in Saturn's rings
(Academic Press Inc. Elsevier B.V., 2012-08-01)
Particles in Saturn's main rings range in size from dust to kilometer-sized objects. Their size distribution is thought to be a result of competing accretion and fragmentation processes. While growth is naturally limited ...
Structuring eccentric-narrow planetary rings
(Elsevier, 2005-12)
A simple and general description of the dynamics of a narrow-eccentric ring is presented. We view an eccentric ring which precesses uniformly at a slow rate as exhibiting a global m = 1 mode, which can be seen as originating ...
Motion around a monopole plus ring system - I. Stability of equatorial circular orbits versus regularity of three-dimensional motion
(Wiley-blackwellMaldenEUA, 2011)
Particles Co-orbital to Janus and to Epimetheus: A Firefly Planetary Ring
(2018-01-01)
The Cassini spacecraft found a new and unique ring that shares the trajectory of Janus and Epimetheus, co-orbital satellites of Saturn. Performing image analysis, we found this to be a continuous ring. Its width is between ...
Resonantly forced narrow eccentric ringlets: Relationships between Surface density, Resonance location, Eccentricity and Eccentricity gradient
(Springer, 2005-12)
We use a simple model of the dynamics of a narrow-eccentric ring, to put some
constraints on some of the observable properties of the real systems. In this work we concentrate on the case of the ‘Titan ringlet of Saturn’. ...
The northern arc of epsilon eridani's debris ring as seen by ALMA
(Oxford University Press, 2017)
We present the first Atacama Large Millimeter/submillimeter Array (ALMA) observations of the closest known extrasolar debris disc. This disc orbits the star is an element of Eri, a K-type star just 3.2 pc away. Due to the ...
The role of Mab as a source for the mu ring of Uranus (Research Note)
(Edp Sciences S A, 2012-07-01)
Context. We previously analysed how the solar radiation force combined with the planetary oblateness changes the orbital evolution of a sample of dust particles located at the secondary ring system of Uranus. Both effects ...
