Planetary Radii across Five Orders of Magnitude in Mass and Stellar Insolation: Application to Transits
We investigate the prospects for characterizing extrasolar giant planets by measuring planetary oblateness from transit photometry and inferring planetary rotational periods. The rotation rates ofExpand
Measurement of Spin-orbit Misalignment and Nodal Precession for the Planet around Pre-main-sequence Star PTFO 8-8695 from Gravity Darkening
PTFO 8-8695b represents the first transiting exoplanet candidate orbiting a pre-main-sequence star (van Eyken et al. 2012, ApJ, 755, 42). We find that the unusual lightcurve shapes of PTFO 8-8695 canExpand
Measurement of the Spin-Orbit Misalignment of KOI-13.01 from its Gravity-Darkened Kepler Transit Lightcurve
We model the asymmetry of the KOI-13.01 transit lightcurve assuming a gravity-darkened rapidly rotating host star in order to constrain the system's spin-orbit alignment and transit parameters. WeExpand
The identification of liquid ethane in Titan’s Ontario Lacus
Infrared spectroscopic data obtained by the Visual and Infrared Mapping Spectrometer (VIMS) on board the Cassini spacecraft strongly indicate that ethane, probably in liquid solution with methane, nitrogen and other low-molecular-mass hydrocarbons, is contained within Titan’s Ontario Lacus. Expand
Spectroscopy, morphometry, and photoclinometry of Titan's dunefields from Cassini/VIMS
Fine-resolution (500 m/pixel) Cassini Visual and Infrared Mapping Spectrometer (VIMS) T20 observations of Titan resolve that moon's sand dunes. The spectral variability in some dune regions showsExpand
Effects of Orbital Eccentricity on Extrasolar Planet Transit Detectability and Light Curves
ABSTRACT It is shown herein that planets with eccentric orbits are more likely to transit than circularly orbiting planets with the same semimajor axis by a factor of \documentclass{aastex}Expand
Composition and Physical Properties of Enceladus' Surface
Observations of Saturn's satellite Enceladus using Cassini's Visual and Infrared Mapping Spectrometer instrument were obtained during three flybys in 2005, and upper limits of 140 kelvin are derived for the temperatures in the tiger stripes. Expand
Detection and mapping of hydrocarbon deposits on Titan
[1] We report the identification of compounds on Titan's surface by spatially resolved imaging spectroscopy methods through Titan's atmosphere, and set upper limits to other organic compounds. WeExpand
Correlations between Cassini VIMS spectra and RADAR SAR images: Implications for Titan's surface composition and the character of the Huygens Probe Landing Site
Titan's vast equatorial fields of RADAR-dark longitudinal dunes seen in Cassini RADAR synthetic aperture images correlate with one of two dark surface units discriminated as “brown” and “blue” inExpand
