KIC 8462862, an F-type main sequence star in the constellation of Cygnus, experienced strange light dimming episodes during the initial Kepler mission between 2009 and 2013. These continue with further events in 2017. The authors use Kepler and post-Kepler data to create folding plots to examine the relationship between the star’s reported 0.88-day rotational period and suspected periodicities noted in connection with the light dimming episodes. This reveals a new possible periodicity of 9.68 days (11 stellar rotations). Confirmation of a mathematical relationship between suspected periodicities and the star’s rotational period would begin to eliminate some of the proposed explanations for the star’s strange fluctuations in light, while at the same time bringing to the fore other possible theories to account for both the short term and long term dimming events.
