We present new visible and infrared observations of the hot Jupiter Kepler-7b to determine its atmospheric properties. Our analysis allows us to (1) refine Kepler-7b's relatively large geometric albedo of Ag = 0.35 ± 0.02, (2) place upper limits on Kepler-7b thermal emission that remains undetected in both Spitzer bandpasses and (3) report a westward shift in the Kepler optical phase curve. We argue that Kepler-7b's visible flux cannot be due to thermal emission or Rayleigh scattering from H2… Expand

3D modeling of GJ1214b's atmosphere: formation of inhomogeneous high clouds and observational implications
The warm sub-Neptune GJ1214b has a featureless transit spectrum which may be due to the presence of high and thick clouds or haze. Here, we simulate the atmosphere of GJ1214b with a 3D GeneralExpand

It is shown that optical phase curves can help constrain the composition and size of the cloud particles and is established a valuable framework within which to investigate exoplanet atmospheres using upcoming flagship space missions such as the European Space Agency's CHEOPS and PLATO and NASA's TESS, which will all fly within the decade.

The atmospheric circulation of a nine-hot Jupiter sample: Probing circulation and chemistry over a wide phase space
We present results from an atmospheric circulation study of nine hot Jupiters that comprise a large transmission spectral survey using the Hubble and Spitzer Space Telescopes. These observationsExpand
Atmospheric Characterization of the Hot Jupiter Kepler-13Ab
Kepler-13Ab (= KOI-13.01) is a unique transiting hot Jupiter. It is one of very few known short-period planets orbiting a hot A-type star, making it one of the hottest planets currently known. TheExpand
Transitions in the cloud composition of hot Jupiters
Over a large range of equilibrium temperatures, clouds shape the transmission spectrum of hot Jupiter atmospheres, yet their composition remains unknown. Recent observations show that the KeplerExpand

Clouds, which are common features in Earth's atmosphere, form in atmospheres of planets that orbit other stars than our Sun, in so-called extrasolar planets or exoplanets. Exoplanet atmospheres canExpand
Modeling the effects of inhomogeneous aerosols on the hot Jupiter Kepler-7b's atmospheric circulation
Motivated by the observational evidence of inhomogeneous clouds in exoplanetary atmospheres, we investigate how proposed simple cloud distributions can affect atmospheric circulations and infraredExpand
Variable Irradiation on 1D Cloudless Eccentric Exoplanet Atmospheres
Exoplanets on eccentric orbits experience an incident stellar flux that can be markedly larger at periastron versus apoastron. This variation in instellation can lead to dramatic changes inExpand
Detection of a westward hotspot offset in the atmosphere of hot gas giant CoRoT-2b
Short-period planets exhibit day–night temperature contrasts of hundreds to thousands of kelvin. They also exhibit eastward hotspot offsets whereby the hottest region on the planet is east of theExpand
On Mapping Exoplanet Atmospheres with High-dispersion Spectro-polarimetry: Some Model Predictions
Planets reflect and linearly polarize the radiation that they receive from their host stars. The emergent polarization is sensitive to aspects of the planet atmosphere such as the gas composition andExpand


The High Albedo of the Hot Jupiter Kepler-7 B
Hot Jupiters are expected to be dark from both observations (albedo upper limits) and theory (alkali metals and/or TiO and VO absorption). However, only a handful of hot Jupiters have been observedExpand
