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
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
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 asExpand
On the properties of contact binary stars
We have compiled a catalogue of light curve solutions of contact binary stars. It contains the results of 159 light curve solutions. The properties of contact binary stars were studied using theExpand
The first year of SN 2004dj in NGC 2403
New BV RI photometry and optical spectroscopy of the Type IIp supernova 2004dj in NGC 2403, obtained during the first year since discovery, are presented. The progenitor cluster, Sandage 96, is alsoExpand
The effect of stellar limb darkening values on the accuracy of the planet radii derived from photometric transit observations
Context. The radius of an exoplanet is one of its most important parameters. Studies of planetary interiors and their evolution require 1% precision in the radius determination. Transiting exoplanetsExpand
Transiting exoplanets from the CoRoT space mission - XI. CoRoT-8b: a hot and dense sub-Saturn around a K1 dwarf
Aims. We report the discovery of CoRoT-8b, a dense small Saturn-class exoplanet that orbits a K1 dwarf in 6.2 days, and we derive its orbital parameters, mass, and radius. Methods. We analyzed twoExpand
The Disappearing Act of KH 15D: Photometric Results from 1995 to 2004
We present results from the most recent (2002–2004) observing campaigns of the eclipsing system KH 15D, in addition to rereduced data obtained at Van Vleck Observatory (VVO) between 1995 and 2000.Expand
Transiting exoplanets from the CoRoT space mission - XIV. CoRoT-11b: a transiting massive “hot-Jupiter” in a prograde orbit around a rapidly rotating F-type star
The CoRoT  exoplanet science team announces the discovery of CoRoT-11b, a fairly massive hot-Jupiter transiting a V  = 12.9 mag F6 dwarf star (M ∗  = 1.27 ± 0.05 M ⊙ , R ∗  = 1.37 ± 0.03 R ⊙ , T effExpand
Long-term evolution of FU Orionis objects at infrared wavelengths
We investigate the brightness evolution of seven FU Orionis systems in the 1−100 µm wavelength range using data from the Infrared Space Observatory (ISO). The ISO measurements were supplemented byExpand
