RUI: Observational Studies of Supernova Remnants

超新星在天文学中很重要，因为它们是 是恒星演化的关键阶段， 能量和丰富的化学元素 新一代恒星形成的气体。 了解 所涉及的物理机制需要了解 超新星从最初的辉煌褪色后， 它们的爆炸变成了微弱的结和细丝， 远离他们的起源。 主要研究者 (PI)将继续进行光谱测量以发现超新星 主要存在于麦哲伦星云和外部星系中 M33寻找新的残骸 他还将拍摄已知的“照片”， 电荷耦合器件（CCD）探测器， 适合于离子发射线的过滤器， 分析残骸的化学丰度，运动和热 特色 私家侦探在过去曾带头参与 这些运动图像的研究。 这 该提案预计将提供双重目的，既阐明 超新星爆炸后几个世纪的演化， 在指导学生如何提取 从多重曝光图像中获取信息。

Supernovae are important in astronomy both because they are a key phase in the evolution of stars and because they produce energy and enriched chemical elements to the interstellar gas from which new generations of stars form. To understand the physical mechanism involved requires a knowledge of how supernova evolve after they fade from the initial brilliance of their explosions to faint knots and filaments of their remnants at large distances from their origins. The Principal Investigator (PI) will continue a spectroscopic survey to discovery of supernova remnants primarily in the Magellanic Clouds and the external galaxy M33 to find new remnants. He will also take "photographs" of known remnants with a charged coupled device (CCD) detector combined with filters appropriate to emission lines of ions that permit an analysis of the remnant's chemical abundances, motions, and thermal characteristics. The PI has taken a lead in the past in involving undergraduates in the studies of these kinematic images. This proposal is expected to provide a dual purpose, both in elucidating the evolution of supernovae centuries after their explosions and in the instruction of students in the techniques of extracting information from multiple exposure images.
