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 a… Expand
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 the… Expand
The Aromatic Infrared Bands as seen by ISO-SWS: Probing the PAH model
We discuss the Aromatic Infrared Band (AIB) proles observed by ISO-SWS towards a number of bright interstellar regions where dense molecular gas is illuminated by stellar radiation. Our sample spans… Expand
A new family of planets? Ocean-Planets
A new family of planets is considered which is in between the rocky terrestrial planets and the gaseous giants, “Ocean-Planets.” We present the possible formation, composition and internal structure… Expand
Transiting exoplanets from the CoRoT space mission. I. CoRoT-Exo-1b: a low-density short-period plan
Context. The pioneer space mission for photometric planet searches, CoRoT, steadily monitors about 12,000 stars in each of its fields of view; it is able to detect transit candidates early in the… Expand
Could We Search for Primitive Life on Extrasolar Planets in the Near Future
Abstract We revisit the idea of R. Bracewell and R. Angelet al.,that exoplanets around nearby stars could be detected in the IR (6–17 μm) and their spectra analyzed, searching for CO2, H2O, O3, CH4,… Expand
THE MASS OF CoRoT-7b
The mass of CoRoT-7b, the first transiting super-Earth exoplanet, is still a subject of debate. A wide range of masses have been reported in the literature ranging from as high as 8 M ⊕ to as low as… Expand
Could we identify hot ocean-planets with CoRoT, Kepler and Doppler velocimetry?
Planets less massive than about 10 MEarth are expected to have no massive H–He atmosphere and a cometary composition (∼50% rocks, 50% water, by mass) provided they formed beyond the snowline of… Expand
Darwin--a mission to detect and search for life on extrasolar planets.
The discovery of extrasolar planets is one of the greatest achievements of modern astronomy. The detection of planets that vary widely in mass demonstrates that extrasolar planets of low mass exist.… Expand
Darwin—an experimental astronomy mission to search for extrasolar planets
As a response to ESA call for mission concepts for its Cosmic Vision 2015–2025 plan, we propose a mission called Darwin. Its primary goal is the study of terrestrial extrasolar planets and the search… Expand
