摘要:

最近,通过多万亿次计算机的可用性和超新星代码的日益复杂化,在核心坍缩超新星的真实建模方面取得了很大进展。这些改进使模拟具有足够的真实性,长期以来一直是个谜的爆炸机制可能很快就会被描绘出来。我们简要介绍了CHIMERA代码,超新星代码,我们已经开发出模拟核心坍缩超新星在1,2,和3个空间维度。然后,我们描述了一套正在进行的2D模拟开始从12,15,20和25太阳质量的祖。这些都表现出爆炸,目前正处于膨胀阶段,冲击波在5,000到20,000公里之间。我们还简要地描述了一个正在进行的模拟在3个空间维度开始从15太阳质量祖。

英文摘要:

Much progress in realistic modeling of core-collapse supernovae has occurred recently through the availability of multi-teraflop machines and the increasing sophistication of supernova codes. These improvements are enabling simulations with enough realism that the explosion mechanism, long a mystery, may soon be delineated. We briefly describe the CHIMERA code, a supernova code we have developed to simulate core-collapse supernovae in 1, 2, and 3 spatial dimensions. We then describe the results of an ongoing suite of 2D simulations initiated from a 12, 15, 20, and 25 solar mass progenitor. These have all exhibited explosions and are currently in the expanding phase with the shock at between 5,000 and 20,000 km. We also briefly describe an ongoing simulation in 3 spatial dimensions initiated from the 15 solar mass progenitor.
