γ射线暴的能源机制

Energy Mechanisms of γ-Ray Bursts

火球模型被认为是γ射线暴的标准模型,而火球产生的机制是多方面的,其中之一就是奇异星相变,它既解释了γ射线暴的短时标、高能量特征,又避免了火球的重子污染这一最大难题.通过对γ射线暴的能源机制研究,探讨了宇宙学距离(～Gpc)处γ射线暴的能量来自奇异星相变的可能性,进而认识了奇异星模型的独特优势.

The fireball model is universally accepted as the standard model in explaining γ-ray bursts. Phase transition of strange stars is one of the factors leading to fireball appearance, which not only can explain the short scales and high energy of γ-ray bursts, but also address the issue of baryon pollution of the fireball. On the basis of researching the energy mechanism of gamma-ray bursts, the possibility that the energy of gamma-ray bursts at cosmology distance （-Gpc） comes from phase transition of strange stars is discussed.
