Simulations of Titan's paleoclimate
Juan M. Lora, Jonathan I. Lunine, Joellen L. Russell +1
We investigate the effects of varying Saturn's orbit on the atmospheric circulation and surface methane distribution of Titan. Using a new general circulation model of Titan's atmo…
GCM simulations of Titan's middle and lower atmosphere and comparison to observations
Juan M. Lora, Jonathan I. Lunine, Joellen L. Russell
Simulation results are presented from a new general circulation model (GCM) of Titan, the Titan Atmospheric Model (TAM), which couples the Flexible Modeling System (FMS) spectral d…
The Habitable Zones of Pre-Main-Sequence Stars
Ramses M. Ramirez, Lisa Kaltenegger
We calculate the pre-main-sequence HZ for stars of spectral classes F to M. The spatial distribution of liquid water and its change during the pre-main-sequence phase of protoplane…
New Insights on Jupiter's Deep Water Abundance from Disequilibrium Species
Dong Wang, Peter Gierasch, Jonathan Lunine +1
The bulk water abundance on Jupiter potentially constrains the planet's formation conditions. We improve the chemical constraints on Jupiter's deep water abundance in this paper. T…
Chaotic Dynamics of Stellar Spin Driven by Planets Undergoing Lidov-Kozai Oscillations: Resonances and Origin of Chaos
Natalia I. Storch, Dong Lai
Many exoplanetary systems containing hot Jupiters are found to possess significant misalignment between the spin axis of the host star and the planet's orbital angular momentum axi…
Corrugations and eccentric spirals in Saturn's D ring: New insights into what happened at Saturn in 1983
M. M. Hedman, J. A. Burns, M. R. Showalter
Previous investigations of Saturn's outer D ring (73,200-74,000 km from Saturn's center) identified periodic brightness variations whose radial wavenumber increased linearly over t…
New insights on Saturn's formation from its nitrogen isotopic composition
Olivier Mousis, Jonathan I. Lunine, Leigh N. Fletcher +4
The recent derivation of a lower limit for the N/N ratio in Saturn's ammonia, which is found to be consistent with the Jovian value, prompted us to revise models of S…
Stellar orbit evolution in close circumstellar disc encounters
Diego J. Muñoz, Kaitlin M. Kratter, Mark Vogelsberger +2
The formation and early evolution of circumstellar discs often occurs within dense, newborn stellar clusters. For the first time, we apply the moving-mesh code AREPO, to circumstel…
Gemini Planet Imager Spectroscopy of the HR 8799 planets c and d
Patrick Ingraham, Mark S. Marley, Didier Saumon +43
During the first-light run of the Gemini Planet Imager (GPI) we obtained K-band spectra of exoplanets HR 8799 c and d. Analysis of the spectra indicates that planet d may be warmer…
Chaotic Dynamics of Stellar Spin in Binaries and the Production of Misaligned Hot Jupiters
Natalia I. Storch, Kassandra R. Anderson, Dong Lai
Many exoplanetary systems containing hot Jupiters are observed to have highly misaligned orbital axes relative to the stellar spin axes. Kozai-Lidov oscillations of orbital eccentr…
Suppression of extreme orbital evolution in triple systems with short range forces
Bin Liu, Diego J. Muñoz, Dong Lai
The Lidov-Kozai (LK) mechanism plays an important role in the secular evolution of many hierarchical triple systems. The standard LK mechanism consists of large-amplitude oscillati…
More Kronoseismology with Saturn's rings
M. M. Hedman, P. D. Nicholson
In a previous paper (Hedman and Nicholson 2013), we developed tools that allowed us to confirm that several of the waves in Saturn's rings were likely generated by resonances with…
Evidence of Titan's Climate History from Evaporite Distribution
Shannon M. MacKenzie, Jason W. Barnes, Christophe Sotin +8
Water-ice-poor, 5-m-bright material on Saturn's moon Titan has previously been geomorphologically identified as evaporitic. Here we present a global distribution of the occurren…
The Brightening of Saturn's F Ring
Robert S. French, Mark R. Showalter, Rafael Sfair +5
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 wi…
Planet-disc interaction on a freely moving mesh
Diego J. Munoz, Kaitlin M. Kratter, Volker Springel +1
General-purpose, moving-mesh schemes for hydrodynamics have opened the possibility of combining the accuracy of grid-based numerical methods with the flexibility and automatic reso…
The First H-band Spectrum of the Massive Gas Giant Planet beta Pictoris b with the Gemini Planet Imager
Jeffrey Chilcote, Travis Barman, Michael P. Fitzgerald +43
Using the recently installed Gemini Planet Imager (GPI), we have taken the first H-band spectrum of the planetary companion to the nearby young star beta Pictoris. GPI is designed…
The measured compositions of Uranus and Neptune from their formation on the CO iceline
M. Ali-Dib, O. Mousis, J. -M. Petit +1
The formation mechanisms of the ice giants Uranus and Neptune, and the origin of their elemental and isotopic compositions, have long been debated. The density of solids in the out…
Polarimetry with the Gemini Planet Imager: Methods, Performance at First Light, and the Circumstellar Ring around HR 4796A
Marshall D. Perrin, Gaspard Duchene, Max Millar-Blanchaer +41
We present the first results from the polarimetry mode of the Gemini Planet Imager (GPI), which uses a new integral field polarimetry architecture to provide high contrast linear p…
Cassini ISS Mutual Event Astrometry of the Mid-sized Saturnian Satellites 2005-2012
N. J. Cooper, C. D. Murray, V. Lainey +3
We present astrometric observations of the Saturnian satellites Mimas, Enceladus, Tethys, Dione and Rhea from Cassini Imaging Science Subsystem (ISS) narrow-angle camera (NAC) imag…
The properties of planets around giant stars
M. I. Jones, J. S. Jenkins, P. Bluhm +2
Context: More than 50 exoplanets have been found around giant stars, revealing different properties when compared to planets orbiting solar-type stars. In particular, they are Supe…
