We present radial-velocity sequences acquired during three transits of the exoplanet HD 189733b and one transit of CoRoT-3b. We applied a combined Markov-chain Monte-Carlo analysis of spectroscopic and photometric data on these stars, to determine a full set of system parameters including the projected spin-orbit misalignment angle of HD 189733b to an unprecedented precision via the Rossiter-McLaughlin effect: β = 0.85 ◦ +0.32 −0.28 . This small but non-zero inclination of the planetary orbit… Expand

The spin–orbit alignment of the transiting exoplanet WASP-3b from Rossiter–McLaughlin observations
We present an observation of the Rossiter-McLaughlin effect for the planetary system WASP-3. Radial velocity measurements were made during transit using the SOPHIE spectrograph at the 1.93-m… Expand
Discovery and Rossiter-Mclaughlin Effect of Exoplanet Kepler-8b
We report on the discovery and the Rossiter-McLaughlin (R-M) effect of Kepler-8b, a transiting planet identified by the NASA Kepler Mission. Kepler photometry and Keck-HIRES radial velocities yield… Expand
WASP-23b: a transiting hot Jupiter around a K dwarf and its Rossiter-McLaughlin effect

Methods for exomoon characterization: Combining transit photometry and the Rossiter-McLaughlin effect
It has been suggested that moons around transiting exoplanets may cause an observable signal in transit photometry or in the Rossiter-McLaughlin (RM) effect. In this paper, a detailed analysis of… Expand
THERMAL EMISSION OF WASP-14b REVEALED WITH THREE SPITZER ECLIPSES
Exoplanet WASP-14b is a highly irradiated, transiting hot Jupiter. Joshi et al. calculate an equilibrium temperature (T eq) of 1866 K for zero albedo and reemission from the entire planet, a mass of… Expand
