In this work section 1 first gives a theoretical introduction on what is the planetary formation and the most accepted theories and then, in section 2, the articles that have been the basis for this work are explained and the results that the Authors obtained. In section 3 we present the Mercury numerical integration package and the changes made in this package to suit the problem, the data that I obtained with the test using the adaptation and a brief comparison with the original data. In the sequence we have section 4 where are introduced the concepts, objectives and initial conditions of the simulations made to determine dependence of the region of stability of the system with respect to the separation of the binary star and then presented the results where we show that in fact, at decreasing the separation between the stars of the binary the region of stability of the disk migrates to the internal region of the same and that the third star orbit inclination only begins to affect the region of stability from inclination values above 30o. In section 5 we point out the main conclusions and then the articles that served as guide for this work are presented in the section of bibliographical references
