Filippenko, Alexei"Supernovae and Their Cosmological Applications"AST-9987438Dr. Filippenko will continue a very successful program that discovers, performs follow-up observations with a robotic telescope (KAIT), and ultimately incorporates the resulting data on stellar supernova events into appropriate cosmological models. Multi-color, long-term light curves of all sufficiently bright supernovae are being obtained. Special emphasis will be placed on catching the generally neglected earliest stages of supernova outbursts. The primary goal of the proposed research is to improve understanding of the progenitor stars, explosion mechanisms, and nucleosynthetic products of supernovae. This work has contributed directly and measurably to the recent discovery of the accelerating universe.Funding for this project was provided by the NSF program for Stellar Astronomy & Astrophysics (AST/SAA).

Filippenko，Alexei“超新星及其宇宙学应用”AST-9987438博士。 Filippenko 将继续开展一项非常成功的计划，利用机器人望远镜 (KAIT) 进行发现、后续观测，并最终将恒星超新星事件的所得数据纳入适当的宇宙学模型中。 正在获得所有足够明亮的超新星的多色、长期光曲线。 将特别强调捕捉通常被忽视的超新星爆发的最早阶段。 该研究的主要目标是增进对前身星、爆炸机制和超新星核合成产物的了解。 这项工作对最近加速宇宙的发现做出了直接且可衡量的贡献。该项目的资金由 NSF 恒星天文学和天体物理学 (AST/SAA) 计划提供。
