我们报告了在系外行星OGLE-TR-10b凌日期间发生的一次恒星耀斑，这一事件在以前的文献中没有报道过。这减少了观测到的凌日深度，特别是在U‘波段，但耀斑在其他波段也可能显著，并可能导致不正确的行星参数。我们认为OGLE-TR-10a是一颗活跃的行星宿主恒星，具有异常高的X射线光度。
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 theu'-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.
