Charged particles at the crust of compact stars may be ejected and accelerated by the induced electric field generated due to the rotation of the magnetized star. For neutron or hybrid stars, the negatively charged particles are usually electrons, and the positively charged particles are mainly protons and iron. Whereas, the existence of strange stars also includes the possibility of ejection of strangelets from the star surface. The energy of such strangelets emitted from all known pulsars is in the range of 10 9 –10 10 GeV. Therefore, such massive strangelets can be one of the candidates for the sources of the highest-energy cosmic rays that have still eluded us. Our model proposes a possible origin of these ultra high energy cosmic rays.

旋转磁化星中带电粒子的加速度

致密恒星外壳处的带电粒子可能会由于磁化恒星旋转而产生的感应电场而被喷射并加速。对于中子星或杂星，带负电的粒子通常是电子，带正电的粒子主要是质子和铁。然而，奇异恒星的存在还包括从恒星表面弹出奇异星的可能性。从所有已知脉冲星发出的这种奇异子的能量在10 9 –10 10 GeV的范围内。因此，如此庞大的奇特物体可能是我们仍无法逃脱的最高能量宇宙射线源的候选者之一。我们的模型提出了这些超高能宇宙射线的可能起源。
