             abstract = "The dwarf planet Haumea is a trans-Neptunian object that is 
                         orbited by two moons and has a recently discovered ring. The 
                         particles of this ring arc near the 3:1 resonance between the spin 
                         of Haumea and the orbital motion of the particles. In this work, 
                         the ring of Haumea is investigated using Perturbation Maps. These 
                         maps show the behaviour and impact of perturbations acting over 
                         particles around Haumea. The information coming from the maps 
                         depends on the integral type for the disturbing acceleration used 
                         to build the maps. The types II and IV are used. The numerical 
                         simulations are focused in the region between 2000 and 2500 km 
                         from the centre of Haumca, which is the region where the ring was 
                         observed, considering two initial values for the 3:1 resonant 
                         angle: theta(res) = 0 degrees and theta(res) = 270 degrees. The 
                         possible stable region for the initial angle theta(res) = 0 
                         degrees is larger than the stable region for the initial angle 
                         theta(res) = 270 degrees. Furthermore, we found that these stable 
                         regions are not continuous, indicating that there are possible 
                         gaps in the ring. Therefore, our results suggest that Haumea may 
                         not have only one single ring, but a system of rings instead. 
                         Possible transit of the particles between the ring and the region 
                         close to the orbit of Namaka is also shown.",
