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
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
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
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
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,
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
Revisiting the transits of CoRoT-7b at a lower activity level
The first super-Earth with measured radius discovered was CoRoT-7b and it has opened the new field of rocky exoplanet characterisation. To better understand this interesting system, new observations
