Compact object binaries, consisting of neutron stars and black holes, represent one of the most likely sources of gravitational waves to be detected by LIGO and future gravitational wave observatories.  This project will design computer models to study gravitational radiation from compact object binaries.  This will include studying how the internal structure of neutron stars affects the gravitational radiation emitted in a binary merger.  Additional work will investigate opportunities for multiple messenger astronomy, in which data from several types of observations are combined to obtain a more complete picture.  In particular, this project will study possible emission of electromagnetic radiation and neutrinos from the merger of neutron stars and black holes.This research is of broad interest reaching beyond physicists to astrophysicists, mathematicians, and the general public (for whom movies will be posted to the web).  The connection of gravitational, electromagnetic and neutrino data from black hole and neutron star mergers will significantly advance our understanding of some of the most intriguing processes in the universe.  This work will provide valuable candidate waveforms for gravitational wave observatories, including LIGO.  As part of a multinational effort to compare such waveforms, this work will be especially valuable to the gravitational wave community in their efforts to detect this radiation.  Information that comes from these gravitational waves will lead to a better understanding of the internal structure of neutron stars and matter at nuclear densities.  The activities described here will provide educational and training opportunities for undergraduate and graduate students, including individuals from underrepresented groups.  This work uses the HAD computational infrastructure, and thus supports this broadly useful, publicly available software for scientific computing.

由中子星和黑洞组成的致密天体双星是LIGO和未来的引力波天文台最有可能探测到的引力波来源之一。这个项目将设计计算机模型来研究紧凑型双星的引力辐射。这将包括研究中子星的内部结构如何影响双星合并时发出的引力辐射。额外的工作将研究多重信使天文学的机会，其中来自几种观测类型的数据结合起来以获得更完整的图像。特别是，该项目将研究中子星和黑洞合并时可能发射的电磁辐射和中微子。这项研究具有广泛的兴趣，从物理学家到天体物理学家、数学家和普通公众（他们的电影将被发布到网络上）。将黑洞和中子星合并的引力、电磁和中微子数据联系起来，将极大地促进我们对宇宙中一些最有趣过程的理解。这项工作将为包括LIGO在内的引力波天文台提供有价值的候选波形。作为比较这些波形的多国努力的一部分，这项工作将对引力波社区在探测这种辐射的努力中特别有价值。来自这些引力波的信息将使我们更好地了解中子星和核密度物质的内部结构。这里描述的活动将为本科生和研究生提供教育和培训机会，包括来自代表性不足群体的个人。这项工作使用HAD计算基础设施，因此支持这个广泛有用的、公开可用的科学计算软件。
