Physical Parameters of the Detached Eclipsing Binary KIC3858884 with a δ-Scuti Type Pulsating Component
Abstract
We present physical parameters for the detached eclipsing binary KIC3858884 which has a δ-Scuti type pulsating secondary component. To derive orbital elements from the radial-velocity curve, high resolution Echelle spectra were obtained at the Bohyunsan Optical Astronomy Observatory in Korea. The BOES spectra and Kepler photometric data were analyzed with well-known codes: JKTEBOP and Wilson-Devinney model for eclipsing light-curve synthesis, and Period04 for pulsation frequency analysis. After the iterative curve fitting, we determined the physical parameters of KIC3858884 as M1=2.02 +/- 0.23M⊙, M2=2.02 +/- 0.16M⊙, R1=3.61 +/- 0.12R⊙, R2=2.84 +/- 0.10R⊙, respectively.
