中文摘要
9312148货车阿尔特纳该奖项将资助建设一个斑点干涉仪,并将其放置在耶鲁南方天文台的Cesco天文台和阿根廷埃尔莱昂西托的圣胡安大学。该仪器的目的是纠正近距离目视双星现代观测在半球分布上的巨大不平衡。新的观测结果,结合芬森的开创性工作,将导致对质量光度关系下半部分的认识的重大改进。改进的质量可以为恒星结构和演化计算及其与观测结果的比较提供所需的约束。***
英文摘要
9312148 Van Altena This award will fund the construction of a Speckle Interferometer and station it at the Cesco Observatory of the Yale Southern Observatory and the University of San Juan at El Leoncito, Argentina. The purpose of this instrument is to rectify the large imbalance in the hemispheric distribution of modern observations of close visual binaries. The new observations, in combination with those from the pioneering work of Finsen, will lead to a significant improvement in the knowledge of the lower part of the mass luminosity relation. Improved masses can provide needed constraints to stellar structure and evolution calculations and their comparison with observations. ***
