| dc.description.abstract | The present work focuses on using the data of variable stars of the OGLE II catalog with the purpose of separating from them a type of variable stars: The eclipsing binary stars. This type of stars is a system of 2 stars gravitationally linked and whose orbital plane is along the line of sight of the observer. Due to this configuration, in each orbital cycle, 2 eclipses aren produced: first when one of the components is interposed between the observer and the second star; and then, in another moment of the orbit, when the second component eclipses the first one. The importance of studying this type of objects is based on the fact that the physical properties of a simple star (radius, temperature, mass) are obtained from the study of eclipsing binary systems. As a result of measuring the luminous flux variation of these objects, what is called the light curve of a variable star is obtained. In the case of an eclipsing binary system, the more light curves are measured in different filters, the more system parameters can be determined. In this work, in addition to identifying the eclipsing binaries of the OGLE II catalog, we will look for their counterparts in another catalog called MACHO, this means obtaining the same binaries that are simultaneo- usly contained in both catalogs. With the results obtained, we hope to generate our own catalog of eclipsing binaries with photometric information in three filters I, V and R. From the new catalog of eclipsing binaries you can choose a set of star systems with special characteristics that can be objects to be analyzed in future research projects. | |
