Description
Aims: We aim to identify and characterize secondary eclipses in
the original light curves of all published CoRoT planets using uniform
detection and evaluation critetia. Methods: Our analysis is based
on a Bayesian model selection between two competing models: one with and
one without an eclipse signal. The search is carried out by mapping the
Bayes factor in favor of the eclipse model as a function of the eclipse
center time, after which the characterization of plausible eclipse
candidates is done by estimating the posterior distributions of the
eclipse model parameters using Markov chain Monte Carlo. Results:
We discover statistically significant eclipse events for two planets,
CoRoT-6b and CoRoT-11b, and for one brown dwarf, CoRoT-15b. We also find
marginally significant eclipse events passing our plausibility criteria
for CoRoT-3b, 13b, 18b, and 21b. The previously published CoRoT-1b and
CoRoT-2b eclipses are also confirmed.

Exoplanets and Astrobiology
The search for life in the universe has been driven by recent discoveries of planets around other stars (known as exoplanets), becoming one of the most active fields in modern astrophysics. The growing number of new exoplanets discovered in recent years and the recent advance on the study of their atmospheres are not only providing new valuable
