Churchwell, Edward B. AST 96-17686 Dr. Churchwell will study the formation processes and early evolution of massive stars in our Galaxy using a variety of observational techniques in the radio and infrared. His research program focuses on a study of the environment of ultra compact HII regions, the earliest manifestations of high mass stars. He will use observations of molecular lines in the radio and the infrared to investigate the velocity structure, chemistry, energetics, and physical conditions in the gas near these stars. He is particularly interested in understanding the properties of molecular outflows and the accompanying accretion disks believed to be associated with young massive stars during their formation. ***

Churchwell，Edward B. AST 96-17686 Churchwell博士将使用无线电和红外线的各种观测技术研究我们银河系中大质量恒星的形成过程和早期演化。 他的研究计划侧重于研究超紧凑HII区域的环境，这是高质量恒星的最早表现。 他将利用射电和红外线中的分子线观测来研究这些恒星附近气体的速度结构、化学、能量学和物理条件。 他特别感兴趣的是了解分子外流的性质和伴随的吸积盘，这些吸积盘被认为与年轻的大质量恒星在形成过程中有关。 ***
