9416994 McAlister Drs. McAlister and Hartkopf at Georgia State University will continue a program of high angular resolution observations of binary star systems using speckle techniques. Binary stars are the only source for the fundamental determination of stellar masses and can provide direct determinations of stellar distances, radii, luminosities, and effective temperatures. The Georgia State University program of binary star speckle interferometry began in 1975 and has continued its original emphasis on obtaining significant numbers of well calibrated observations at large aperture telescopes. These data are being used to greatly improve the orbital elements of known binaries and to calculate the orbits of resolved spectroscopic systems and other newly discovered binaries.

小行星9416994 格鲁吉亚州立大学的麦卡利斯特博士和哈特科普夫博士将继续一项利用斑点技术对双星星星系统进行高角分辨率观测的计划。 联星是基本确定恒星质量的唯一来源，可以直接确定恒星距离、半径、光度和有效温度。 格鲁吉亚州立大学的双星星星散斑干涉测量计划始于1975年，并继续其原来的重点是获得大量的良好校准的意见，在大口径望远镜。 这些数据被用来大大改进已知双星的轨道根数，并计算解析光谱系统和其他新发现的双星的轨道。
