Resumen de Effects of the Orbit Orientation on the Evolution of Dwarf Satellite Galaxies
Paula España Fontán, María de los Ángeles Gómez Flechoso 
Cosmological models propose a hiearchical scenario for the evolution of the galaxies, wheredwarf galaxies are accreted in the halo of larger ones, known as host or main galaxies. Observations of galaxy systems indicate that the distribution of satellite dwarf galaxies in the maingalaxy halo is not homogeneous, but presents a planar distribution perpendicular to the disk ofthe main galaxy. In this work, we analyze a possible origin of this inhomogeneous distributiondue to different time survival times of the satellites depending on the orientation of their orbits.
