Query: Fundamental Parameters of Kepler Eclipsing Binaries. I. KIC 5738698   Eclipsing binaries serve as a valuable source of stellar masses and radii
that inform stellar evolutionary models and provide insight into additional
astrophysical processes. The exquisite light curves generated by space-based
missions such as Kepler offer the most stringent tests to date. We use the
Kepler light curve of the 4.8-day eclipsing binary KIC 5739896 with ground
based optical spectra to derive fundamental parameters for the system. We
reconstruct the component spectra to determine the individual atmospheric
parameters, and model the Kepler photometry with the binary synthesis code ELC
to obtain accurate masses and radii. The two components of KIC 5738698 are
F-type stars with M1 = 1.39+/-0.04M, M2 = 1.34+/-0.06M, and R1 = 1.84+/-0.03R,
R2 = 1.72+/-0.03R. We also report a small eccentricity (e < 0.0017) and unusual
albedo values that are required to match the detailed shape of the Kepler light
curve. Comparisons with evolutionary models indicate an approximate age of 2.3
Gyr for the system.
