1 Otero, Sebastian Alberto KOI-126 A shows rotational modulation with P= 16.66 d. (amplitude 0.002 mag.). The inner binary orbit precesses, like a spinning top, every ~1000 days in response to the gravity of KOI-126 A and eclipses come and go.
2 2011arXiv1102.0562C Low-mass binary (period 1.76713 days) in an eccentric orbit around a third star (period 33.9214 d), causing triple eclipses.
