AST-0123304Graham, James R.The solar neighborhood within 50 parsecs will be examined for spectral type L and T dwarf companions using the adaptive optics system at the Advanced Electro-Optical System telescope on Haleakela, Maui Hawaii. Late-type binaries of low magnitude contrast will be examined to search for these companions. So few of these stars are known to exist today using classical techniques of observation, that discovery of new ones, which may result from the application of adaptive optics, will have a profound effect on our understanding of these objects. ***

在夏威夷毛伊岛哈雷克拉的先进光电系统望远镜上，将使用自适应光学系统对50秒差距内的太阳邻域进行光谱类型L和T矮星伴星的检查。 晚型双星的低等对比度将被检查，以寻找这些同伴。 使用经典的观测技术，今天已知的这些恒星很少，新的发现，这可能是自适应光学的应用，将对我们理解这些物体产生深远的影响。***
