The Near Stellar Environment

祖克曼将在光学、红外和毫米波段进行观测：1)主序星周围的尘埃盘（可能是前行星），重点是画人座β； 2)金牛座T星和其他前主序星周围的冷伴星和尘埃云；3)演化恒星周围的尘埃和分子，包括行星状星云。技术包括使用恒星日冕仪，在光学和红外，红外散斑干涉测量。行星被认为是由积聚在年轻恒星周围的尘埃气体形成的。最近在一些恒星周围发现了暗示行星形成的尘埃盘。朱克曼将用最先进的仪器来研究这个问题以及与之密切相关的课题，包括一台可以阻挡来自中心恒星的光线的相机，以及一种基于计算机的技术，可以产生非常清晰的红外图像。祖克曼是附近一颗恒星可能伴星的共同发现者。

Zuckerman will make observations in the optical, infrared, and millimeter regimes of: 1) dust disks (perhaps pre-planetary) around main sequence stars, with emphasis on Beta Pictoris, 2) cool companions and dust clouds around T Tauri and other pre- main-sequence stars, and 3) dust and molecules around mass-losing evolved stars, including planetary nebulae. Techniques include use of the stellar coronagraph, in the optical and infrared, and infrared speckle interferometry. Planets are thought to form from dusty gas accumulated around young stars. Dust disks suggestive of planetary formation have recently been detected around a few stars. Zuckerman will pursue this and closely related subjects with state-of-the-art instrumentation, including a camera that blocks out the light from the central star and a computer-based technique that yields very sharp infrared pictures. Zuckerman is a co-discoverer of a possible planetary companion of a nearby star.
