TRESCA | Focusing TTV diagrams in ETD.
TTV plots in Exoplanet Transit Database were updated today. Simultaneously observed transits are now plotted in TTV figure as averaged values (red squares). The original points are colored grey. This leaded to significant focusing of TTV curve for many objects. Size of the square depends on size (quality) of points. See ETD.
It is applied the weighted averaging (according to Data Quality index of individual data sets)

TRESCA | New transiting exoplanet CoRoT-20 b (Mon) was added to ETD
For more information see M. Deleuil et al. (2011), XX. CoRoT-20b: A very high density, high eccentricity transiting giant planet

TRESCA | New transiting circumbinary exoplanet Kepler-16(AB) b was added to ETD
Kepler-16A b means transits of planet "b" on primary component of the binary with depth 0.019 mag and duration ~ 7 hours.
Kepler-16B b means transits of planet "b" on secondary binary component with depth only 0.001 mag and duration 1.5 hours.
The system also exhibits minimas of eclipsing binary with period 41 days.
ATTENTION! Transit predictions in ETD for this system are now wrong. We will improve predictions soon.
For more details about this great system, see a discovery paper by L. Doyle et al., (2011): Kepler-16: A Transiting Circumbinary Planet

TRESCA | New transiting super-Earth HD 97658b. A bright star (V = 7.7 mag) in Leo constellation was discovered to have a planet using RV technique. Recently Gregory W. Henry et al. (2011) have discovered a very shallow transits (depth 0.002 mag).
For more details see: Detection of a Transiting Low-Density Super-Earth

Welcome to TRESCA web page about transiting exoplanets and its observation.
TRESCA is an acronym from words TRansiting ExoplanetS and CAndidates.
More than 50 exoplanets has an orbit oriented in space in direction to the Earth and we can see dark planet body transiting in front of stellar disc.
During this transits, observed brightness of the parent star decreases of about 0.003 - 0.04 mag.
