Groundbased and spacecraft telescopic observations, combined with an intensive modeling
effort, have greatly enhanced our understanding of hot giant planets and brown dwarfs over …

Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

Transmission spectra are differential measurements that utilize stellar illumination to probe
transiting exoplanet atmospheres. Any spectral difference between the illuminating light …

Giant exoplanets orbiting very close to their parent star (hot Jupiters) are subject to tidal
forces expected to synchronize their rotational and orbital periods on short timescales (tidal …

With no analogues in the Solar System, the discovery of thousands of exoplanets with
masses and radii intermediate between Earth and Neptune was one of the big surprises of …

This article summarizes a workshop held on March, 2014, on the potential of the James
Webb Space Telescope (JWST) to revolutionize our knowledge of the physical properties of …

Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

Hot Jupiters have been predicted to have a strong day/night temperature contrast and a
hotspot shifted eastward of the substellar point. This was confirmed by numerous phase …

Until recently, infrared observations of exoplanetary atmospheres have typically been
interpreted using models that assumed solar elemental abundances. With the chemical …

We report near-infrared spectroscopy of the gas giant planet HD 189733b in transit. We
used the Hubble Space Telescope Wide Field Camera 3 (HST WFC3) with its G141 grism …
