Studies of Supernova and Supernova Remnants

这项研究的长期目标是了解超新星爆炸，并利用这些知识来确定其他星系的距离。这些距离是我们了解宇宙起源和确定宇宙年龄的基础。该方法基于观测，然后将数据与理论模型进行密切比较。随着研究的进行，诸如我们银河系和其他星系中超新星的比率、成为超新星的恒星的类型、这些爆炸对星际气体的影响、超新星在制造重元素中的作用、超新星的能量输出以及各种类型超新星的性质等问题将得到解决。这项工作已经进行了十多年，并将在这笔拨款下继续进行。

The long term goal of this research is to understand supernova explosions and use that knowledge to determine the distances of other galaxies. These distances are basic to our efforts to understand the origin of the universe and determine its age. The approach is based on observations followed by close comparison of the data to theoretical models. As the research proceeds, such questions as the rate of supernovae in our galaxy and other galaxies, the types of stars which become supernovae, the effects of these explosions on the interstellar gas, the role of supernovae in manufacturing heavy elements, the energy output of supernovae and the properties of various types of supernovae will be addressed. This work has been underway for more than a decade and will continue under this grant.
