The Kepler/APOGEE project. Fundamental parameters for 7 benchmark-grade eclipsing binary systems.
Abstract
Fundamental stellar parameters (masses and radii) with uncertainties smaller than ~1% are exceedingly rare, yet they allow us to critically probe the physical processes that govern stellar evolution. The Kepler/APOGEE project couples ultra-precise light curves from NASA's Kepler mission with the high-resolution spectroscopic data acquired by the APOGEE instrument within the Sloan Digital Sky Survey. Modeling these data with sophisticated tools such as PHOEBE (Prsa et al. 2016; http://phoebe-project.org) enables us to determine fundamental stellar parameters to better than 1%. In this contribution we present the data and the results on 7 benchmark-grade eclipsing binary systems: KIC 3247294, KIC 4281895, KIC 4931073, KIC 2308957, KIC 4076952, KIC 5193386 and KIC 5288543. The first three systems are highly eccentric, and the remaining four systems feature total eclipses.
