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. ***

9312148 Van Altena 该奖项将资助散斑干涉仪的建造，并将其安置在耶鲁南方天文台的塞斯科天文台和阿根廷埃尔莱奥西托的圣胡安大学。该仪器的目的是纠正近视双星现代观测结果在半球分布上的巨大不平衡。新的观测结果与芬森的开创性工作相结合，将显着改善对质量光度关系下部的认识。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。 ***
