important for testing theories of star formation and of stellar evolution in the presence of
nearby companions. We obtained 218 days of Kepler photometry of HD 181068 (magnitude
of 7.1), supplemented by ground-based spectroscopy and interferometry, which show it to be
a hierarchical triple with two types of mutual eclipses. The primary is a red giant that is in a
45-day orbit with a pair of red dwarfs in a close 0.9-day orbit. The red giant shows evidence …
