Query: The contribution of secondary eclipses as astrophysical false positives
  to exoplanet transit surveys   We investigate in this paper the astrophysical false-positive configuration
in exoplanet-transit surveys that involves eclipsing binaries and giant planets
which present only a secondary eclipse, as seen from the Earth. To test how an
eclipsing binary configuration can mimic a planetary transit, we generate
synthetic light curve of three examples of secondary-only eclipsing binary
systems that we fit with a circular planetary model. Then, to evaluate its
occurrence we model a population of binaries in double and triple system based
on binary statistics and occurrence. We find that 0.061% +/- 0.017% of
main-sequence binary stars are secondary-only eclipsing binaries mimicking a
planetary transit candidate down to the size of the Earth. We then evaluate the
occurrence that an occulting-only giant planet can mimic an Earth-like planet
or even smaller planet. We find that 0.009% +/- 0.002% of stars harbor a giant
planet that present only the secondary transit. Occulting-only giant planets
mimic planets smaller than the Earth that are in the scope of space missions
like Kepler and PLATO. We estimate that up to 43.1 +/- 5.6 Kepler Objects of
Interest can be mimicked by this new configuration of false positives,
re-evaluating the global false-positive rate of the Kepler mission from 9.4%
+/- 0.9% to 11.3% +/- 1.1%. We note however that this new false-positive
scenario occurs at relatively long orbital period compared with the median
period of Kepler candidates.
