Ten Brummelaar0088498AbstractThe AEOS system with its operational adaptive optics system will observe a large (186) sample of spectral type O and B stars in the I spectral band to detect and characterize multiple stars. The high spatial resolution obtainable with the adaptive optics will enable the measurement of magnitude differences as high as 8 in order to investigate the mass ratio between the stars within a binary star pair. With a B0 spectral type primary, the detection of an early M star companion is predicted. Orbit determination using double-lined spectroscopic binary information from other telescopes and the estimate of the spectral types from the photometric measurements made with AEOS will enable an estimate of mass. These studies are important to our understanding of the formation of planetary systems, and recycling and processing of gas and dust within galaxies.***

10 Brummelaar 0088498摘要AEOS系统及其操作自适应光学系统将在I光谱波段观测光谱型O和B星的大样本（186），以探测和表征多颗星。 自适应光学系统的高空间分辨率将使测量星等差异高达8，以调查的质量比之间的一个双星星对。 利用B0光谱型主星，预测了早期M型星星伴星的探测。 利用来自其他望远镜的双线分光双星信息确定轨道，并根据AEOS的光度测量估计光谱类型，将能够估计质量。 这些研究对我们理解行星系统的形成，以及星系内气体和尘埃的循环和处理都很重要。
