In 1996, two teams of astronomers announced the possible
detection of a planetary transit eclipse of the close binary pair CM Draconis Aab (Guinan et al, 1998; Martin and Deeg, 1996; and Guinan et al, 1996).
In 1996, two teams of astronomers announced the possible detection
of a planetary transit eclipse of the close binary pair CM Draconis Aab, which has yet to be confirmed (further details below).
Bean tracked GJ 1214 b through two
of those planetary transits using one of the 8.2 - meter telescopes at the Very Large Telescope atop Cerro Paranal in Chile, parsing the observed light into its individual wavelengths.

Three years later Charbonneau found himself locked in a race with Deming to be the first to detect the flip
side of a planetary transit — the moment, called secondary eclipse, when a planet passes behind its star.
It spends much of its time monitoring the light from around 60 of the nearest ultracool dwarf stars and brown dwarfs («stars» which are not quite massive enough to initiate sustained nuclear fusion in their cores), looking for
evidence of planetary transits.
A Hubble Space Telescope
survey of planetary transits in the galactic bulge found that seven percent of the stars have these «hot Jupiters.»
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.
Solutions for stellar parallax and proper motions await more observations, but the analysis of the astrometric residuals from a local solution in the vicinity of a star have already proved to be an important tool in the process of confirming the
hypothesis of a planetary transit.
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.
