Pulsating blue subdwarfs and planets which are not there

In 2011 and 2014, reports appeared that two pulsating sdBV stars observed by the Kepler Space Telescope, KIC 5807616 and KIC 10001893, could be circled by extrasolar planets on tight orbits. However, a new analysis of the putative planetary signatures found in the light curves of these stars shows that there are no planets around them.
