Kepler Planet-Detection Mission: Introduction and First Results
The planetary findings derived from the first six weeks of observations with the Kepler mission are summarized, which include the detection of five new exoplanets, which confirm the existence of planets with densities substantially lower than those predicted for gas giant planets.
Planetary Radii across Five Orders of Magnitude in Mass and Stellar Insolation: Application to Transits
To aid in the physical interpretation of planetary radii constrained through observations of transiting planets, or eventually direct detections, we compute model radii of pure hydrogen-helium,…
Measuring the Oblateness and Rotation of Transiting Extrasolar Giant Planets
We investigate the prospects for characterizing extrasolar giant planets by measuring planetary oblateness from transit photometry and inferring planetary rotational periods. The rotation rates of…
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.
Detection and mapping of hydrocarbon deposits on Titan
 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. We…
Spectroscopy, morphometry, and photoclinometry of Titan's dunefields from Cassini/VIMS
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. We…
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.

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 (1 - e2) -1. If the orbital parameters of…
