A Model for Thermal Phase Variations of Circular and Eccentric Exoplanets
methods data analysis planetary systems
2010/11/3
We present a semi-analytic model atmosphere for close-in exoplanets that captures the essential
physics of phase curves: orbital and viewing geometry, advection, and re-radiation. We calibrate the mo...
Transiting planet discoveries have largely been restricted to the short-period or low-periastron distance regimes due to the bias inherent in the geometric transit probability. Through the refine-ment...
Warm Spitzer Photometry of the Transiting Exoplanets CoRoT-1 and CoRoT-2 at Secondary Eclipse

2010/11/1
We measure secondary eclipses of the hot giant exoplanets CoRoT-1 at 3.6 and 4.5 μm, and CoRoT-2 at 3.6 μm, both using Warm Spitzer. We find that the Warm Spitzer mission is working very well for exop...
Orbital Orientations of Exoplanets: HAT-P-4b is Prograde and HAT-P-14b is Retrograde
Earth and Planetary Astrophysics (astro-ph.EP)
2010/10/7
We present observations of the Rossiter-McLaughlin effect for two exoplanetary systems, revealing the orientations of their orbits relative to the rotation axes of their parent stars.
Atmospheric circulation of tidally-locked exoplanets: a suite of benchmark tests for dynamical solvers
Earth and Planetary Astrophysics (astro-ph.EP) Galaxy Astrophysics (astro-ph.GA)
2010/10/6
The complexity of atmospheric modelling and its inherent non-linearity, together with the limited amount of data of exoplanets available, motivate model intercomparisons and benchmark tests.
Comparison of current models for Hot Jupiters to the sample of transiting exoplanets
Earth and Planetary Astrophysics (astro-ph.EP)
2010/10/5
A growing number (over 100!) of extra-solar planets (ESPs) have been discovered by transit photometry, and these systems are important because the transit strongly constrains their orbital inclination...
Transiting exoplanets from the CoRoT space mission. XV. CoRoT-15b: a brown dwarf transiting companion
Earth and Planetary Astrophysics (astro-ph.EP)
2010/10/1
We report the discovery by the CoRoT space mission of a transiting brown dwarf orbiting a F7V star with an orbital period of 3.06 days. CoRoT-15b has a radius of 1.12 +0.30 -0.15 Rjup, a mass of 63.3 ...
Not So Black? The Statistics of Albedo and Energy Recirculation on Hot Exoplanets
data analysis — (stars:) planetary systems
2009/12/30
[Abridged] We use a simple analytic model to analyze all of the published photometric observations of exoplanets. Our model has two parameters: the planets' Bond albedo, A, and its heat recirculation ...
