Supernovae In Nearby Galaxies: Discovery, Rates, and Detailed Studies

超新星（SN）代表了某些类型恒星演化的最后爆发阶段，由于它们参与了星系的化学演化、激波诱导的恒星形成、宇宙射线、中子星、黑洞和宇宙的距离尺度，它们显然是宇宙中最有趣和最重要的组成部分之一。该项目将继续努力提高对不同类型SN的祖星、爆炸机制和核合成产物的理解。这种方法主要是观察性的，加上通过非正式合作建立的理论模型。这个小组在利克天文台的机器人成像望远镜可以说是世界上最成功的在附近星系中搜索SN的望远镜，并且继续收集光谱分类的SN将用于研究它们的时间演化和统计特性。光谱偏振法有很大的发现潜力，因为它提供了关于超新星形状和内部结构的信息，这也将是本研究的主要重点。研究结果将继续传播给广大读者，作为前沿研究与有效的公共宣传和教学相辅相成的任务的一部分。特别是首席研究员每年都要做许多广受好评的公开演讲，接受电视、广播、杂志和报纸的采访，并出现在教育录像、书籍和电视纪录片中。这些研究将继续涉及大量的本科生，以及研究生和博士后。参与者包括高中生、退休人员和弱势群体，并且一直在寻找新的候选人。

AST-0607485FilippenkoSupernovae (SN) represent the final, explosive stage in the evolution of certain varieties of stars, and because of their involvement in the chemical evolution of galaxies, shock-induced star formation, cosmic rays, neutron stars, black holes, and the distance scale of the Universe, they are clearly among the most interesting and important constituents of the Universe. This project will continue efforts to improve the understanding of the progenitor stars, explosion mechanisms, and nucleosynthetic products, of different types of SN. The approach is largely observational, plus theoretical modeling through informal collaborations. This group's robotic imaging telescope at the Lick Observatory is arguably the world's most successful search for SN in nearby galaxies, and the continuing collection of spectroscopically classified SN will be used to study their temporal evolution and statistical properties. Spectropolarimetry has a large potential for discovery, as it provides information on supernova shapes and internal structure, and this will also be a major focus of this research.Results will continue to be disseminated to a broad audience, as part of continuing the complementary missions of cutting-edge research and effective public outreach and teaching. The principal investigator in particular gives many well-received public lectures each year, is interviewed for television, radio, magazines and newspapers, and appears in educational videos, books, and television documentaries. These studies will continue to involve a large number of undergraduates, as well as graduates and postdocs. Participants have included high school students, retirees, and the disadvantaged, and new candidates are always being sought.
