The orbital motion, absolute mass and high-altitude winds of exoplanet HD 209458b
High-dispersion ground-based spectroscopy of a transit of the extrasolar planet HD 209458b sees a significant wavelength shift in absorption lines from carbon monoxide in the planet’s atmosphere, which is concluded arises from a change in the radial component of the planet's orbital velocity.

The signature of orbital motion from the dayside of the planet τ Boötis b
The detection of carbon monoxide absorption in the thermal dayside spectrum of τ Boötis b supports the hypothesis that the absorbing compounds believed to cause such atmospheric inversions are destroyed in τ Bo Ötis b by the ultraviolet emission from the active host star. Expand
Changing Phases of Alien Worlds: Probing Atmospheres of Kepler Planets with High-Precision Photometry
We present a comprehensive analysis of planetary phase variations, including possible planetary light offsets, using eighteen quarters of data from the Kepler space telescope. After correcting forExpand
We conducted a comprehensive search for optical phase variations of all close-in (a/R{sub *} 1), so we conclude that they are likely to be self-luminous objects rather than planets. The other sixExpand
Ground-based detection of sodium in the transmission spectrum of exoplanet HD209458b
Context. The first detection of an atmosphere around an extrasolar planet was presented by Charbonneau and collaborators in 2002. In the optical transmission spectrum of the transiting exoplanet HDExpand
Optical to near-infrared transit observations of super-Earth GJ 1214b: water-world or mini-Neptune?
Context. GJ1214b, the 6.55 Earth-mass transiting planet recently discovered by the MEarth team, has a mean density of∼35% of that of the Earth. It is thought that this planet is either a mini-NExpand
The changing phases of extrasolar planet CoRoT-1b
Optical photometric data obtained over 36 planetary orbits of the transiting hot Jupiter CoRoT-1b are consistent with the nightside hemisphere of the planet being entirely black, with the dayside flux dominating the optical phase curve. Expand
WTS-2 b: a hot Jupiter orbiting near its tidal destruction radius around a K dwarf
We report the discovery of WTS-2 b, an unusually close-in 1.02-d hot Jupiter (M-P = 1.12M(J), R-P = 1.30R(J)) orbiting a K2V star, which has a possible gravitationally bound M-dwarf companion at 0.6Expand
The GROUSE project - III. Ks-band observations of the thermal emission from WASP-33b
Context. In recent years, day-side emission from about a dozen hot Jupiters has been detected through ground-based secondary eclipse observations in the near-infrared. These near-infraredExpand
Detection of water absorption in the day side atmosphere of HD 189733 b using ground-based high-resolution spectroscopy at 3.2 μm
We report a 4.8{$σ$} detection of water absorption features in the day side spectrum of the hot Jupiter HD 189733 b. We used high-resolution (R {\tilde} 100 000) spectra taken at 3.2 {$μ$}m withExpand
