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.***

具有其操作自适应光学系统系统的TEN BRUMMELAAR0088498ABCRATTENT THE AEOS系统将观察到I光谱带中的频谱O和B型恒星的大型（186）样品，以检测和表征多个恒星。 可以使用自适应光学器件获得的高空间分辨率将使幅度差的测量高达8，以研究二进制恒星对中恒星之间的质量比。 使用B0频谱类型的主要原则，可以预测早期M星伴侣的检测。 使用来自其他望远镜的双线光谱二进制信息的轨道测定以及通过AEOS制定的光度测量值对光谱类型的估计将实现质量估计。 这些研究对于我们对行星系统形成的理解以及银河系中气体和尘埃的回收和处理至关重要。***
