Robinson, Edward AST-9731416 Dr. Robinson will carry out an observational program to study black holes which occur in soft X-ray transient systems (SXT's), binary systems in which mass is being transferred from a relatively normal star to a compact star through an accretion disk. He will use the Hobby-Eberly Telescope for a long-term synoptic program of spectroscopy of these faint SXT's, as well as detailed studies of selected objects. The primary goals of the program are to determine more accurate mass ratios and black hole masses and to determine the properties and evolution of accretion disks surrounding the black holes.

Robinson博士将执行一个观测项目，研究软x射线瞬变系统（SXT）中出现的黑洞。在这种双星系统中，质量通过吸积盘从一颗相对正常的恒星转移到一颗致密的恒星。他将使用霍比-埃伯利望远镜对这些微弱的SXT进行长期的光谱综合研究，并对选定的物体进行详细研究。该计划的主要目标是确定更准确的质量比和黑洞质量，并确定黑洞周围吸积盘的性质和演化。
