论文摘要
Lhaaso合作观察到超高能量光子从$ 12 $ $γ$ ray的银河系来源高达$ 1.4 $ PEV。特别是,已经发布了来源的$γ$ -Ray光谱J2226+6057,J1908+0621,J1825-1326。我们研究了在源附近的pevatrons附近提出的原始脉冲星的可能性。脉冲星是通过旋转磁极偶极子描述的。假设质子是从光圆柱体中分布的均匀分布,我们获得了质子能谱的洛伦兹分布。发现Pulsar周围的质子可以在短时间加速到PEV。建议的起源脉冲星的HADRONIC $γ$ -Ray光谱与LHAASO观察到的$γ$ -Ray光谱J2226+6057,J1908+0621,J1825-1326。
The LHAASO Collaboration has observed ultrahigh-energy photons up to $1.4$PeV from $12$ $γ$-ray Galactic sources. In particular, the $γ$-ray spectra of the sources J2226+6057, J1908+0621, J1825-1326 have been published. We investigate the possibility of suggested origin pulsars near the sources as the PeVatrons. The pulsar is described by a rotating magnetic dipole. Assuming protons are uniform distributed out of the light cylinders, we obtain the Lorentz distribution of proton energy spectrum. It is found that the protons around pulsar could be accelerated to PeV at short times. The hadronic $γ$-ray spectra of the suggested origin pulsars are in good agreement with the LHAASO observed $γ$-ray spectra of the sources J2226+6057, J1908+0621, J1825-1326.
