Abstract：
The origin and signature of ultra high-energy cosmic rays are still somewhat mysterious. In this paper, we present an effective acceleration mechanism for such ultra high-energy events based on supermassive stellar objects with saturation of magnetic monopoles of ‘t Hooft-Polyakov type in the universe. Catalyzed by magnetic monopoles, nucleons may decay to energetic charged particles and radiation, and can travel to great distance from their source because of the absence of horizon and central singularity of these supermassive stellar objects, due to Rubakov-Callan effect. These rapid rotating collapsed objects have radial magnetic fields in the local co-rotating frame. The induced electromagnetic fields in the rest frame are quite different from that of the usual dipole fields. The strength of such induced fields are very strong and decrease with the square of distance. As a result, the energetic charged particles released during nucleon decay may be further accelerated for a rather long period and the resulting energy of such cosmic rays may be far beyond 10 ²¹eV.
