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.

AST-0607485FILIPPENKOSUPERNOVAE（SN）代表了某些恒星变化的最终爆炸性阶段，并且由于它们参与星系化学演变，震动引起的恒星形成，宇宙宇宙，宇宙射线，中子星，黑洞，黑洞和黑洞和黑洞和黑洞和黑洞和黑洞和宇宙的距离尺度显然是宇宙中最有趣，最重要的成分之一。 该项目将继续努力，以提高对不同类型的SN的祖细胞，爆炸机制和核合成产品的理解。 该方法在很大程度上是观察性的，以及通过非正式合作的理论建模。 该小组在Lick Observatory的机器人成像望远镜可以说是世界上最成功的SN在附近星系中搜索的SN，并且持续收集光谱分类的SN将用于研究其时间进化和统计特性。 SpectroPolorimetry具有巨大的发现潜力，因为它提供了有关超新星形状和内部结构的信息，这也将是这项研究的主要重点。作为继续互补的任务的一部分，将继续向广泛的受众传播。尖端的研究以及有效的公共宣传和教学。 尤其是首席调查员每年都会为电视，广播，杂志和报纸进行采访，并在教育视频，书籍和电视纪录片中进行采访。 这些研究将继续涉及大量的大学生以及毕业生和博士后。 参与者包括高中生，退休人员和弱势群体，并且总是在寻找新的候选人。
