Cowley, AnneAST-9731491Dr. Cowley will carry out an observational study of supersoft X-ray binary systems to measure more accurately their stellar masses and other fundamental physical parameters. Both spectroscopic and photometric observations will be made which will provide information on stellar properties such as temperature, luminosity, and mass, as well as the mass ratio, orbital inclination, and mass transfer rate and structure of the accretion disk. Observations will be compared to existing models to elucidate the nature of the compact objects in these systems and distinguish between competing models of white dwarf, neutron star, or black hole accretors.

Cowley，AnneAST-9731491Dr.考利将对超软X射线双星系统进行观测研究，以更准确地测量它们的恒星质量和其他基本物理参数。 将进行分光和光度观测，提供有关恒星性质的信息，如温度、光度和质量，以及质量比、轨道倾角和质量转移率以及吸积盘的结构。 观测结果将与现有的模型进行比较，以阐明这些系统中致密天体的性质，并区分白色矮星、中子星星或黑洞吸积物的竞争模型。
