摘　　要：在超重质量星无限塌缩的过程中,其能量标度达到足够大时,此时就可以应用粒子物理中的大统一理论,并提出一个新的模型:核子衰变后一个超重质量星将把它的几乎所有质量转化为能量,从而变为可能是亚稳定或不稳定的轻子星.按照这一模型,就可以解释超高能宇宙射线和高能天体物理中的下列疑难:类星体和γ-射线暴等.轻子星也许就是真实的白洞.The grand unified theory of particle physics is applied to the supermassive stars,whose energy scale is large enough to take an infinitely collapsing process.A new model is proposed that after nucleon-decays,a supermassive star will convert nearly all its mass into energy,and become a lepton star that might possibly be substable or unstable.According to the model the ultrahigh energy cosmic rays and these puzzles in astrophysics at high energy:quasars and gamma-ray bursts,etc.,may be explained.A lepton star is probably a true white hole.
