With the use of numerical models, we investigate whether Mean Motion Resonances (MMR) with nearby moons to the J1407b ring system were the cause of the observed 0.0267AU wide gap located at 0.4AU. Only one location of a moon at 0.63AU (corresponding to a 2:1 MMR) was found to form a gap at 0.4AU over short time periods of <100yr. However, the proximity of a low mass moon (0.08M_⊕) caused significant scattering of the outer ring edge at 0.6AU, along with the formation of an additional gap at the… Expand
ALMA and NACO observations towards the young exoring transit system J1407 (V1400 Cen)
Our aim was to directly detect the thermal emission of the putative exoring system responsible for the complex deep transits observed in the light curve for the young Sco-Cen star 1SWASPExpand
The structure and stability of extended, inclined circumplanetary disc or ring systems
Large dips in the brightness for a number of stars have been observed, for which the tentative explanation is occultation of the star by a transiting circumplanetary disk or ring system. In order forExpand


A recent origin for Saturn’s rings from the collisional disruption of an icy moon
Abstract 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 toExpand
Modeling giant extrasolar ring systems in eclipse and the case of J1407b: sculpting by exomoons?
The light curve of 1SWASP J140747.93-394542.6, a $\sim$16 Myr old star in the Sco-Cen OB association, underwent a complex series of deep eclipses that lasted 56 days, centered on April 2007. ThisExpand
A belt of moonlets in Saturn’s A ring
Embedded moonlets found in Saturn’s A ring are probably the remnants of a shattered ring-moon of Pan size or larger, locally contributing new material to the older ring, which supports the theory of catastrophic ring creation in a collisional cascade. Expand
The shape and dynamics of a heliotropic dusty ringlet in the Cassini Division
Abstract The so-called “Charming Ringlet” (R/2006 S3) is a low-optical-depth, dusty ringlet located in the Laplace gap in the Cassini Division, roughly 119,940 km from Saturn center. This ringlet isExpand
On the tidal environment of an outwardly migrating F ring
Saturn’s F-ring is a unique narrow ring that lies radially close to the tidally disruptive Roche limit of Saturn for water ice. Significant work has been done on the system that shows it to be one ofExpand
A recent cometary origin for Saturn's rings?
Gravitational torques and erosion by micrometeoroids may cause rapid evolution of Saturn's rings, possibly suggesting formation of the rings within the last 108 years. Optically thin and/or narrowExpand
The Population of Propellers in Saturn's A Ring
We present an extensive data set of ∼150 localized features from Cassini images of Saturn’s A ring, a third of which are demonstrated to be persistent by their appearance in multiple images, and halfExpand
Ring Edge Waves and the Masses of Nearby Satellites
Moons embedded in gaps within Saturn’s main rings generate waves on the gap edges due to their gravitational disturbances. These edge waves can serve as diagnostics for the masses and, in some cases,Expand
A pilot investigation to constrain the presence of ring systems around transiting exoplanets
Abstract We demonstrate a process by which to evaluate the presence of large, Saturn-like ring systems around transiting extrasolar giant planets. We use extrasolar planet candidate KOI-422.01 as anExpand
Constraints on the size and dynamics of the J1407b ring system
Context. J1407 (1SWASP J140747.93-394542.6 in full) is a young star in the Scorpius-Centaurus OB association that underwent a series of complex eclipses over 56 days in 2007. To explain these, it wasExpand
