We present a detailed study of KIC 2306740, an eccentric double-lined eclipsing binary system with a pulsating component.
Archive Kepler satellite data were combined with newly obtained spectroscopic data with 4.2\,m William Herschel Telescope
(WHT). This allowed us to determine rather precise orbital and physical parameters of this long period, slightly eccentric, pulsating binary system. Duplicity effects are extracted from the light curve in order to estimate pulsation frequencies from the residuals.
We modelled the detached binary system assuming non-conservative evolution models with the Cambridge STARS(TWIN) code.
