Reyes-Ibarra Física, Astronomía y Matemáticas Brane theory astrophysics This paper is dedicated to revisit the modifications caused by branes in the collapse of a stellar structure under the Snyder-Oppenheimerscheme. Due to the homogeneity and isotropy of the model, we choose study the case of a closed geometry described byk= 1, throughthe tool of dynamical systems. We revisit the different components of the star and its evolution during the stellar collapse, paying particularattention to the non-local effects and the quadratic terms of the energy momentum tensor that come from branes corrections. In the same veinwe realize a phase portrait together with a stability analysis with the aim of obtain information about the attractors or saddle points of thedynamical system under different initial conditions in the density parameters, remarking the parameters that come from branes contributions. 2016 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57045452003 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
