Binary Star Speckle Interferometry

9416994乔治亚州立大学的麦克阿里斯特博士和哈特科普夫博士将继续一项使用散斑技术对双星系统进行高角度分辨率观测的计划。双星是从根本上确定恒星质量的唯一来源，可以直接确定恒星的距离、半径、光度和有效温度。佐治亚州立大学的双星散斑干涉测量计划始于1975年，并继续其最初的重点，即在大口径望远镜上获得大量经过良好校准的观测数据。这些数据正被用来极大地改进已知双星的轨道元素，并计算已分解的光谱系统和其他新发现的双星的轨道。

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.
