标题： 2D and 3D Core-Collapse Supernovae Simulation Results Obtained with the CHIMERA Code

摘要： 近年来，通过多太浮点机器的可用性和超新星代码的日益复杂，核心坍缩超新星的真实建模取得了很大进展。 这些改进使得模拟具有足够的现实性，使长期神秘的爆炸机制可能很快被明确。 我们简要描述了CHIMERA代码，这是一个我们开发的用于在1、2和3个空间维度中模拟核心坍缩超新星的超新星代码。 然后我们描述了一套正在进行的2D模拟的结果，这些模拟始于12、15、20和25倍太阳质量的前身星。 这些模拟都表现出爆炸，并且目前处于膨胀阶段，冲击波位于5000到20000公里之间。 我们还简要描述了一个正在进行的3维空间模拟，该模拟始于15倍太阳质量的前身星。 显示英文摘要

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.
