For extrasolar planets discovered using the radial velocity method, the spectral characterization of the host star leads to a mass estimate of the star and subsequently of the orbiting planet. If the orbital velocity of the planet could be determined, the masses of both star and planet could be calculated using Newton’s law of gravity, just as in the case of stellar double-line eclipsing binaries. Here we report high-dispersion ground-based spectroscopy of a transit of the extrasolar planet HD… Expand
Exoplanet transmission spectroscopy: accounting for the eccentricity and the longitude of periastron - Superwinds in the upper atmosphere of HD 209458b?
Context. A planet transiting in front of the disk of its parent star offers the opportunity to study the compositional properties of its atmosphere by means of the analysis of the stellar light thatExpand
High-resolution spectroscopic search for the thermal emission of the extrasolar planet HD 217107 b
We analyzed the combined near-infrared spectrum of a star-planet system with thermal emission atmospheric models, based on the composition and physical parameters of the system. The main objective ofExpand
The signature of orbital motion from the dayside of the planet τ Boötis b
TLDR
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
Absolute masses and radii determination in multiplanetary systems without stellar models
The masses and radii of extrasolar planets are key observables for understanding their interior, formation and evolution. While transit photometry and Doppler spectroscopy are used to measure theExpand
Rotation and winds of exoplanet HD 189733 b measured with high-dispersion transmission spectroscopy
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 locking).Expand
Radial velocity eclipse mapping of exoplanets
Planetary rotation rates and obliquities provide information regarding the history of planet formation, but have not yet been measured for evolved extrasolar planets. Here we investigate theExpand
Extrasolar Planetary Transits
An extrasolar planet will transit the visible hemisphere of its host star if its orbital plane lies sufficiently close to the observer’s line of sight. The resulting periodic dips in stellar fluxExpand
Search for Earth-like planets in the habitable zone of M-dwarfs
Since the first detection of an extrasolar planet orbiting a Sun-like star by Mayor and Queloz (1995), more than 1500 have been discovered. Enormous interest is currently focused on finding andExpand
Constraining High Speed Winds in Exoplanet Atmospheres Through Observations of Anomalous Doppler Shifts During Transit
Three-dimensional (3D) dynamical models of hot Jupiter atmospheres predict very strong wind speeds. For tidally locked hot Jupiters, winds at high altitude in the planet's atmosphere advect heat fromExpand
Resolving the sin(I) Degeneracy in Low-mass Multi-planet Systems
Long-term orbital evolution of multi-planet systems under tidal dissipation often converges to a stationary state, known as the tidal fixed point. The fixed point is characterized by a lack ofExpand

TLDR
A spectroscopic orbit with period P=3.52433+/-0.00027 days for the planetary companion that transits the solar-type star HD 209458 is reported, based on a new analysis of the iron lines in the HIRES template spectrum and also on the absolute magnitude, effective temperature, and color of the star.

An analysis of recent observations of the hot Jupiter HD 189733b taken during the transit, when the planet passed in front of its parent star, finds that absorption by water vapour is the most likely cause of the wavelength-dependent variations in the effective radius of the planet. Expand
