Dr. Robert Hynes (Louisiana State University) will undertake an extensive imaging and spectroscopic survey to identify optical counterparts of X-ray sources detected by the Galactic Bulge Survey of the Chandra X-ray Observatory. Much of the sample is expected to be low-mass X-ray binaries; these are systems in which a neutron star or a black hole is stripping material from a nearby companion. The project will greatly increase the sample of X-ray binary systems with known properties. Some of these may be eclipsing systems, which would provide important estimates of neutron star and black hole masses. In addition, the data from this project will test models of the formation of low-mass X-ray binaries in different stellar populations.Data from this survey will form the core of a Ph.D. dissertation, and will be distributed to the community for future follow-up surveys at several wavelengths. The research will also provide undergraduate students with direct research experience.

Robert Hynes博士（路易斯安那州立大学）将进行广泛的成像和光谱调查，以确定钱德拉X射线天文台银河隆起调查所探测到的X射线源的光学对应物。 预计大部分样本将是低质量的X射线双星;在这些系统中，中子星星或黑洞正在从附近的伴星上剥离物质。 该项目将大大增加具有已知性质的X射线双星系统的样本。其中一些可能是食系统，这将提供重要的估计中子星星和黑洞的质量。 此外，该项目的数据将测试不同星群中低质量X射线双星形成的模型。论文，并将分发给社区，以供今后在几个波长进行后续调查。 该研究还将为本科生提供直接的研究经验。
