Rossby Wave Instability in Accretion Discs with Large-Scale Poloidal Magnetic Fields
Cong Yu, Dong Lai
We study the effect of large-scale magnetic fields on the non-axisymmetric Rossby wave instability (RWI) in accretion discs. The instability develops around a density bump, which i…
Dynamical Instabilities in High-Obliquity Systems
Daniel Tamayo, Joseph A. Burns, Douglas P. Hamilton +1
High-inclination circumplanetary orbits that are gravitationally perturbed by the central star can undergo Kozai oscillations---large-amplitude, coupled variations in the orbital e…
Of Horseshoes and Heliotropes: Dynamics of Dust in the Encke Gap
M. M. Hedman, J. A. Burns, D. P. Hamilton +1
The Encke Gap is a 320-km-wide opening in Saturn's outer A ring that contains the orbit of the small moon Pan and an array of dusty features composed of particles less than 100 mic…
Assembly of Protoplanetary Disks and Inclinations of Circumbinary Planets
Francois Foucart, Dong Lai
The Kepler satellite has discovered a number of transiting planets around close binary stars. These circumbinary systems have highly aligned planetary and binary orbits. In this pa…
GJ 1214b revised. Improved trigonometric parallax, stellar parameters, orbital solution, and bulk properties for the super-Earth GJ 1214b
Guillem Anglada-Escudé, Bárbara Rojas-Ayala, Alan P. Boss +2
GJ 1214 is orbited by a transiting super-Earth-mass planet. It is a primary target for ongoing efforts to understand the emerging population of super-Earth-mass planets around M dw…
Connections between Spectra and Structure in Saturn's Main Rings Based on Cassini VIMS Data
M. M. Hedman, P. D. Nicholson, J. N. Cuzzi +4
Saturn's main rings exhibit variations in both their opacity and spectral properties on a broad range of spatial scales, and the correlations between these parameters can provide i…
Building Terrestrial Planets
Alessandro Morbidelli, Jonathan I. Lunine, David P. O`brien +2
This paper reviews our current understanding of terrestrial planets formation. The focus is on computer simulations of the dynamical aspects of the accretion process. Throughout th…
Planetesimal Compositions in Exoplanet Systems
Torrence V. Johnson, Olivier Mousis, Jonathan I. Lunine +1
We have used recent surveys of the composition of exoplanet host stars to investigate the expected composition of condensed material in planetesimals formed beyond the snow line in…
The dual origin of the nitrogen deficiency in comets: selective volatile trapping in the nebula and postaccretion radiogenic heating
Olivier Mousis, Aurélie Guilbert-Lepoutre, Jonathan I. Lunine +4
We propose a scenario that explains the apparent nitrogen deficiency in comets in a way consistent with the fact that the surfaces of Pluto and Triton are dominated by nitrogen-ric…
A modified "Type I migration" model for propeller moons in Saturn's rings
Matthew S. Tiscareno
We propose a mechanism for the observed non-keplerian motion (Tiscareno et al. 2010, ApJL) of "propeller" moons embedded in Saturn's rings. Our mechanism, in which radial variation…
The Resonant Transneptunian Populations
B. Gladman, S. M. Lawler, J-M. Petit +8
The transneptunian objects (TNOs) trapped in mean-motion resonances with Neptune were likely emplaced there during planet migration late in the giant-planet formation process. We p…
Nebular water depletion as the cause of Jupiter's low oxygen abundance
Olivier Mousis, Jonathan I. Lunine, Nikku Madhusudhan +1
Motivated by recent spectroscopic observations suggesting that atmospheres of some extrasolar giant-planets are carbon-rich, i.e. carbon/oxygen ratio (C/O) 1, we find that th…
Saturn's icy satellites and rings investigated by Cassini - VIMS. III. Radial compositional variability
G. Filacchione, F. Capaccioni, M. Ciarniello +16
In the last few years Cassini-VIMS, the Visible and Infared Mapping Spectrometer, returned to us a comprehensive view of the Saturn's icy satellites and rings. After having analyze…
Rossby Wave Instability in three dimensional discs
H. Meheut, C. Yu, D. Lai
The Rossby wave instability (RWI) is a promising mechanism for producing large-scale vortices in protoplanetary discs. The instability operates around a density bump in the disc, a…
The physics of wind-blown sand and dust
Jasper F. Kok, Eric J. R. Parteli, Timothy I. Michaels +1
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and ripples, and loads the atmosphere with suspended dust aerosols. This article presents an…
