TL;DR
This paper analyzes Kepler light curves of the eclipsing binary FL Lyr, providing evidence for a third body, likely an exo-Jupiter, with preliminary estimates of its mass and orbital period.
Contribution
It reports the detection of a potential exo-Jupiter companion in the FL Lyr system based on eclipse timing variations.
Findings
Evidence for a third body with > 4 Jupiter masses
Estimated orbital period > 7 years
Analysis of eclipse timing variations
Abstract
Light curves of the eclipsing binary FL Lyr acquired by the Kepler space telescope are analyzed. Eclipse timing measurements for FL Lyr testify to the presence of a third body in the system. Preliminary estimates of its mass and orbital period are > 4M_Jupiter and > 7 yrs. The times of primary minimum in the light curve of FL Lyr during the operation of the Kepler mission are presented.
