Abstract:
We report a stellar flare occurring during a transit of the exoplanet
OGLE-TR-10b, an event not previously reported in the literature. This
reduces the observed transit depth, particularly in the u'-band, but
flaring could also be significant in other bands and could lead to
incorrect planetary parameters. We suggest that OGLE-TR-10a is an
active planet-hosting star and has an unusually high X-ray luminosity.
Description:
A stellar flare was observed on the extrasolar planet hosting star
OGLE-TR-10 during the transit of its planet.
