Dynamically interacting, multi-eclipsing hierarchical triples - observed with Kepler - have recently been shown to be amenable to detailed photo-dynamical modeling that yields surprisingly accurate masses and radii for all members in the system. These published systems harbor planets and very low-mass stars (e.g. the planet Kepler-16b and the stars Kepler-16 B, KOI-126 B and C) and have coevolved companions at large mass ratios (e.g. Kepler-16 A, KOI-126 A). As such, these systems are important benchmarks for stellar models in the poorly calibrated low-mass domain and for a wide range of masses. We report on the progress of a program to model and accurately characterize the remaining Kepler-identified stellar multi-eclipsing triple systems. This program has a simple goal: we will populate the stellar mass-radius diagram with accurate values so as to definitively judge the efficacy of stellar models.
