Timing Lightcurve Minima to Look for Candidate Close Binary Asteroids

True detached binary asteroids are systems in which the components are connected only by gravity. Using only lightcurves, it can be difficult or impossible to determine if an asteroid is a true binary, a contact binary, or a single elongated object. However, if a true binary has an eccentric orbit, we might be able to use the time between lightcurve minima to provide a hint of its nature.
