This award will support the continuation of a project to detect and characterize supernovae, the final, explosive stage in the evolution of certain types of stars. The principal goal of the project is to improve the understanding of the progenitor stars, explosion mechanisms, nucleosynthetic products, and cosmological utility of different types of supernovae. This work will have three parts: (a) the continuation robotic searches for supernovae, extending a recently implemented technique of discovering supernovae very shortly after the explosion; (b) the acquisition, reduction, analysis, and interpretation of extensive new data (photometry and spectroscopy, with particular emphasis on improving the utility of supernovae; (c) the analysis of new and existing data concerning pre-supernovae outbursts and the nature of stripped-envelope core-collapse supernovae; and (d) the analysis of new and existing polarimetry data on supernovae.The award will contribute to the training of undergraduate and graduate students and will support communication of the results of this project (and of supernovae in general) to the general public. The results are also expected to have broad implications for topics as diverse as the chemical evolution of galaxies, the birth rate of pulsars, the masses of black holes, the nature of gamma-ray bursts, and the expansion of the Universe.

该奖项将支持一个项目的延续，以检测和表征超新星，这是某些类型的恒星演变中的最后一个爆炸性阶段。 该项目的主要目标是提高对祖细胞，爆炸机制，核合成产物以及不同类型超新星的宇宙学效用的理解。 这项工作将有三个部分：（a）持续的机器人搜索超新星，并在爆炸后不久就扩展了一种最近实现的技术； （b）对广泛的新数据的获取，减少，分析和解释（光度法和光谱法，尤其强调改善超新星的实用性；（c）分析有关Supernovae爆发前的新和现有数据的分析，以及剥离式核心核心循环超级促进和现有的（d Darlimimimime and of Spectare of dormant of Superry of dorme os of Suppare of and of）的性质；对本科生和研究生的培训，并将支持该项目的结果（以及一般的超新星）向公众进行培训。
