The Eclipsing X-Ray Binary System Centaurus X-3

Problem statement: We present new physical and geometrical elements for the eclipsing X-ray binary system Krzemenski's star (Centaurus X-3). Approach: In this study, the procedure depended on getting the best fit between the observational photometric light curves and synthetic ones built up in accordance to the Roche model. Results: The estimated elements showed a good agreement with the early estimated ones. Conclusion: In building the synthetic light curves, we assumed that the optical component of the system is filling to Roche lobe, the system is rotationally synchronized and we neglecting the effect of the magnetic fields of both components.
