Supernovae and their Cosmological Applications

Filippenko，Alexei“Supernovae and Their Cosmological Applications“AST-9987438Dr. Filippenko将继续一个非常成功的计划，发现，用机器人望远镜（KAIT）进行后续观测，并最终将恒星超新星事件的数据纳入适当的宇宙学模型。 所有足够明亮的超新星的多色长期光变曲线正在被获得。 将特别强调捕捉通常被忽视的超新星爆发的最早阶段。 拟议研究的主要目标是提高对超新星的祖星、爆炸机制和核合成产物的理解。 这项工作对最近加速宇宙的发现做出了直接和可衡量的贡献。该项目的资金由美国国家科学基金会恒星天文天体物理学计划（AST/SAA）提供。

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).
