    "abstract": "In this work, we analyze the effect of charge in compact stars considering\nthe limit of the maximum amount of charge they can hold. We find that the\nglobal balance of the forces allows a huge charge (~ 10^{20} Coulomb) to be\npresent in a neutron star producing a very high electric field (~ 10^{21} V/m).\nWe have studied the particular case of a polytropic equation of state and\nassumed that the charge distribution is proportional to the mass density. The\ncharged stars have large mass and radius as we should expect due to the effect\nof the repulsive Coulomb force with the M/R ratio increasing with charge. In\nthe limit of the maximum charge the mass goes up to ~ 10 M_sun which is much\nhigher than the maximum mass allowed for a neutral compact star. However, the\nlocal effect of the forces experienced by a single charged particle, makes it\nto discharge quickly. This creates a global force imbalance and the system\ncollapses to a charged black hole.",
