To confirm that the transits of COROT 9 b recorded in 2008 by the COROT satellite were indeed planetary, the researchers first took two follow - up readings of the star using a spectrograph in France, a rough sketch that was consistent with the presence of a planet.
All of the potentially Earth - like worlds were spotted using the transit method, which measures dips in a star's light output as a planetary body crosses in front from our line of sight.
This observational result, which uses the achromatic property of planetary transit signals that is not investigated by the Kepler observations, provides an independent indication that Kepler's false positive rate is low.
The initial transit signal was identified in KELT - North survey data, and the planetary nature of the occulter was established using a combination of follow - up photometry, high - resolution imaging, high - resolution spectroscopy, and precise radial velocity measurements.
We confirmed the planetary nature of the transiting companion using this mass limit and Doppler tomographic observations to verify that the companion transits HD 332124.

Using the very high precision Kepler photometry, and follow - up observations, our confidence that these signals represent planetary transits is > 99.1 %.
Forty precision Doppler measurements were used to confirm that the short - period transit event is due to a planetary companion.

On Wednesday, February 2, 2011, NASA's Kepler Mission revealed that, thus far, it has detected 1,235 planetary candidates orbiting 907 host stars, from a survey of some 155,453 stars in constellations Cygnus and Lyra using the transit method which requires a rare orbital alignment across the face of the host star as seen from the Solar System.
He is one of the discovers of the first ring around an asteroid (Chariklo) and with collaborators was the one to first use measurements of planetary transits from space to measure the size of the sun.
We first generate a stellar field with planetary companions based on radial velocity discoveries, use a planetary evolution model assuming a variable fraction of heavy elements to compute the characteristics of transit events, then apply a detection criterion that includes both statistical and red noise sources.
