Title: First detection of Kozai evolution in an astrophysical system

Abstract: Kozai oscillation -- the secular evolution of highly inclined triple systems -- has been theorized to play an important tole in the dynamical evolution of systems from asteroid satellites, , exoplanets, and stellar systems, yet this dynamical evolution has never been directly observed in any astrophysical system owing to the long time scales involved. The satellite of the asteroid Huenna, however, is predictd to have a Kozai period of only 46 years. We propose a new determination of the orbital parameters of the satellite of Huenna. With the last determination almost 8 years ago and the expected orbital changes in that time larger than the expected uncertainties, we expect to obtain the first direct detection of Kozai evolution and a confirmation of the importanace of this seemingly ubiquitous process.
