An extended upper atmosphere around the extrasolar planet HD209458b
The planet in the system HD209458 is the first one for which repeated transits across the stellar disk have been observed. Together with radial velocity measurements, this has led to a determinationExpand

Transiting exoplanets from the CoRoT space mission VIII. CoRoT-7b: the first Super-Earth with measured radius
Aims. We report the discovery of very shallow (ΔF/F ≈ 3.4× 10 −4 ), periodic dips in the light curve of an active V = 11.7 G9V star observed by the CoRoT satellite, which we interpret as caused by aExpand

Masses, Radii, and Orbits of Small Kepler Planets: The Transition From Gaseous to Rocky Planets
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7 revealed by preciseExpand

The CoRoT-7 planetary system: two orbiting super-Earths
We report on an intensive observational campaign carried out with HARPS at the 3.6 m telescope at La Silla on the star CoRoT-7. Additional simultaneous photometric measurements carried out with theExpand

The PLATO 2.0 mission
PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addressesExpand

Interstellar Deuterium, Nitrogen, and Oxygen Abundances toward GD 246, WD 2331–475, HZ 21, and Lanning 23: Results from the FUSE Mission*
The interstellar abundances of D i ,N i, and O i in the local ISM are studied using high-resolution spectra of four hot white dwarfs. The spectra of GD 246, WD 2331� 475, HZ 21, and Lan 23 wereExpand

The Rossiter-McLaughlin effect of CoRoT-3b and HD 189733b
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 spectroscopicExpand

Evaporation of the planet HD 189733b observed in H I Lyman-α
We observed three transits of the extrasolar planet HD 189733b in HI Lyman-α and in a few other lines in the ultraviolet with HST/ACS, in the search for atmospheric signatures. We detect a transitExpand

Transiting exoplanets from the CoRoT space mission. II. CoRoT-Exo-2b: a transiting planet around an
Context. The CoRoT mission, a pioneer in exoplanet searches from space, has completed its first 150 days of continuous observations of ∼12 000 stars in the galactic plane. An analysis of the raw dataExpand

Temporal variations in the evaporating atmosphere of the exoplanet HD 189733b
Atmospheric escape has been detected from the exoplanet HD 209458b through transit observations of the hydrogen Lyman-α line. Here we present spectrally resolved Lyman-α transit observations of theExpand
