after making accounts for each of them.
The importance of binary stars arises from the fact that almost 45% of the galactic stellar
systems are binary or multiple star(Raghavan et al., 2010). Using two references (AlWardat et al., 2014, 1998).

elliptical orbits (can be almost circular in some cases)(“Introduction to Binary Stars,”

Previous studies
The early methods of analyzing light curves of close binary systems goes back to 1880 with
Pickering attempts to identify the elements of al-Ghoul. During the period between 1880

and 1912, many astronomers tried to extract certain eclipsing binaries elements, but to no
avail(Kopal, 1959).
Later on, many contributions have been made to study and analyze the light curves of
the X-ray eclipsing binaries, such as:
1.
(Al-Wardat et al., 1998); New elements for three eclipsing X-Ray binary systems:
HZ Herculis, Centaurus X-3 and VELA X-1.
2.
(Budding and Najim, 1980),(The system VV ORI and the consistency of
photometric analysis of eclipsing binary light curve).

Introduction
In this chapter, we are going to describe the geometrical and mathematical model which
used to calculate the intensity of optical light reaches the earth from an eclipsing X-ray
binary system, taking into account all effects and parameters.

Treatment of observational data
The brightness of a star is a measurement of the radiant flux F received from the star. The
radiant flux received from the star depends on intrinsic luminosity and the distance from
the observer. The equation for star flux F with luminosity L is:
(2-1)
Where F: is the radiant flux of the star
L: is luminosity of the star
r : is the star distance from the earth.
The magnitude is a relative scale that measures the logarithmic value of the radiative Flux.
The definition of the magnitude is given by the formula:
(2-2)
Where Fa and Fbare the brightnessof components a and b respectively, the magnitude
difference gives the differential magnitude of two stars as a function of their observed flux.
2.3
Duration to the eclipse
According to Azimuthal symmetry, we Can calculate the duration of the eclipse (
function of inclination angle (і)(Avni, 1978):

Observations
The stellar binary system RX J0512.2-3241 (UU Col) has been identified with a V~17m.6
star (see Error! Reference source not found.) and a CV-like optical spectrum. B and V
hotometry of the system was obtained on four nights on Jan. 1996 with the ESO/Dutch
0.9m Telescope at La Silla Observatory in Chile. Figure 3-1and.
