Parameters Grid for Exoplanet Transit Projects (Transits)

Sunday 30 November 2008 by Alessandro Sozzetti
We list here a ground-based as well as space-borne observatories/projects devoted to the detection and characterization of planetary transits, providing several relevant key parameters (e.g., observables, photometric performance, limiting mag, expected number of (...)

Signatures interpretation & biomarkers (Modelling Habitable Planets)

Saturday 29 November 2008 by Franck Selsis
A wide diverstity of spectral features should be found among terrestrial exoplanets. In addition to the expected variety of planet bulk compositions, orbits and stars, the atmospheres, and thus the planetary spectra, should exhibit an even broader range of properties. The atmosphere represents (...)

Observing strategy, and description of the reduction pipelines. (Microlensing)

Friday 6 June 2008 by Jean-Philippe Beaulieu
A typical observing season of the Galactic Bulge starts at the beginning of May every year and lasts four months. Among the 691 alerts available in 2006 (579 from OGLE-III and 112 additional from MOA-II), about 180 are available every night in the middle of the season. Of these, around 20 (...)

Definition of Coronagraph ( (Coronagraphy)

Friday 6 June 2008 by Anthony Boccaletti
A coronagraph is a device which blocks light from the center of the telescope beam while permitting light from surrounding sources to pass through relatively undisturbed. The coronagraph was invented by the French astronomer Bernard Lyot in 1939 (Figure 1), to enable astronomers to observe the (...)

Announcement to constitute de group (Single Aperture Imaging)

Wednesday 21 May 2008 by Anthony Boccaletti
Dear all, I’m contacting you on behalf of the Blue Dot Team. Some of you have already heard about this group which is coordinated by Vincent Coudé du Foresto and was initiated by the Darwin former team as a response to the non-selection of missions geared to direct imaging of exoplanets at the (...)
