Secular dimming of KIC 8462852 following its consumption of a planet
@article{Metzger2016SecularDO, title={Secular dimming of KIC 8462852 following its consumption of a planet}, author={Brian D. Metzger and Ken J. Shen and Nicholas C. Stone}, journal={Monthly Notices of the Royal Astronomical Society}, year={2016}, volume={468}, pages={4399-4407} }
The Kepler-field star KIC 8462852, an otherwise apparently ordinary F3 main-sequence star, showed several highly unusual dimming events of variable depth and duration. Adding to the mystery was the discovery that KIC 8462852 faded by 14% from 1890 to 1989, as well as by another 3% over the 4 year Kepler mission. Following an initial suggestion by Wright & Sigurdsson, we propose that the secular dimming behavior is the result of the inspiral of a planetary body or bodies into KIC 8462852, which…
