Observations of KIC 8462852 (aka Boyajian's Star) reveal a yearlong fade pattern that is remarkably similar to the fade pattern derived from Kepler mission observations. The ground-based observations reported here can be described as a gradual fade that ended in late 2016 with the beginning of a yearlong U-shaped fade of 1.1 percent. Near the end of this U-shaped fade a series of very brief dips occurred. The Kepler data exhibit a similar pattern 1600 days earlier, except with an abrupt end of… 



Mysterious eclipses in the light-curve of KIC8462852: a possible explanation

Apart from thousands of `regular' exoplanet candidates, Kepler satellite has discovered a few stars exhibiting peculiar eclipse-like events. They are most probably caused by disintegrating bodies
