This award will support a theoretical investigation into the explosions of massive stars and how the properties of these stars can affect the early evolution of supernova remnants. Dr. Plewa and his students will develop and improve models that include neutrino-driven shock propagation, and will study the details of the explosion mechanisms and shock breakout. The principal goal of the work is to generate core-collapse supernova models in three dimensions to account for the most relevant physics and the geometry of mass flows between the core bounce and the early remnant phases.Dr. Plewa will make models and data products available to the astrophysical community, which will be useful for other research groups. The work will involve many aspects of hydrodynamics, modeling of a wide range of physics, and high-performance computing. This group will continue efforts to provide outreach opportunities for undergraduate students, especially women and members of underrepresented groups, and to communicate results to the general public.

该奖项将支持对大质量恒星爆炸的理论研究，以及这些恒星的性质如何影响超新星遗迹的早期演化。 Plewa博士和他的学生将开发和改进包括中微子驱动冲击波传播的模型，并将研究爆炸机制和冲击波爆发的细节。 这项工作的主要目标是生成三维的核心坍缩超新星模型，以解释核心反弹和早期残余阶段之间最相关的物理学和质量流的几何形状。Plewa博士将为天体物理学界提供模型和数据产品，这将对其他研究小组有用。 这项工作将涉及流体力学的许多方面，广泛的物理建模和高性能计算。 该小组将继续努力为本科生，特别是妇女和代表性不足群体的成员提供外联机会，并向公众宣传成果。
