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和未来引力波观测站最有可能探测到的引力波来源之一。 该项目将设计计算机模型，以研究来自致密天体双星的引力辐射。 这将包括研究中子星的内部结构如何影响双星合并中发出的引力辐射。 其他工作将调查多信使天文学的机会，其中将来自多种类型观测的数据结合起来以获得更完整的图像。 特别是研究中子星和黑洞合并时可能产生的电磁辐射和中微子，不仅受到物理学家的关注，还受到天体物理学家、数学家和公众的广泛关注（视频将被上传到网上）。 从黑洞和中子星星合并中获得的引力、电磁和中微子数据的联系将大大推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在内的引力波观测站提供有价值的候选波形。 作为比较这种波形的多国努力的一部分，这项工作对引力波社区探测这种辐射的努力特别有价值。 来自这些引力波的信息将导致更好地了解中子星和核密度物质的内部结构。 这里所述的活动将为本科生和研究生，包括代表性不足群体的个人提供教育和培训机会。 这项工作使用HAD计算基础设施，从而支持这种广泛有用的，公开可用的科学计算软件。
