still at the beginning of understanding the whole extent of the $\gamma$ Doradus phenomenon, but the combination of the current observational results and theoretical models are expected to answer a lot of open questions. Verification of the present results, especially for the low amplitude frequencies, the detection of the multi-frequencies, and the derivation of the excitation modes are some open questions on the class of $\gamma$ Dor type asteroseismology. We strongly suggest that accurate photometric survey of these systems are needed for answering the listed open questions. Moreover, phase coverage of their light curves and radial velocities will provide their geometrical characteristics. Finally, high-resolution spectroscopy are also suggested not only for the pulsations, but also for the components’ radial velocity curves, which will lead us to calculate their absolute properties with high accuracy.

Conclusion
==========

V2653Oph is a detached eclipsing binary in the young open cluster Collinder359. It is composed of main sequence F type stars. We have derived the astrophysical parameters of the components and other properties for the first time, listed in Table5, by combining the results obtained from the analyses of light curve and radial velocities. The masses and radii of the stars were derived with accuracy
