Title: Towards Unprecedented Accuracy of Fundamental Parameters for Kepler Eclipsing Binary Stars

Abstract: Eclipsing binary stars have played a paramount role in our understanding of stellar astrophysics -- most of what we know about the $T$-$R$-$L$-$M$ relationships comes from studying these systems. The Kepler mission set a new milestone by pushing photometric errors to sub- millimagnitude levels. This opens up a new opportunity to study these \emph{continuously observed} binaries: 1) find and analyze well-detached systems that serve as ideal calibrators for stars across the H-R diagram; 2) resolve the discrepancy between observations and theory on the low-mass end of the main sequence; 3) use total eclipses to derive parameters to unprecedented accuracy; 4) study intrinsic variables and chromospherically active components, and 5) explore system dynamics on a long time scale without missing a beat, thus detecting eclipse timing variations that are indicative of tertiary components. We request 10 nights/year (7 in Spring, 3 in Fall) for 3 years. We aim to observe, reduce and fully analyze $\sim 150$ eclipsing binaries that have been prioritized from a list of 1879 targets in the Kepler field. We focus on systems with the greatest promise of significant scientific advancement.
