9312148 Van Altena该奖项将资助建造一个散斑干涉仪,并将其安置在耶鲁南方天文台的Cesco天文台和阿根廷El Leoncito的圣胡安大学。该仪器的目的是纠正大的不平衡在半球分布的现代观测近距离视觉双星。新的观测结果与Finsen的开创性工作相结合,将导致对质量光度关系较低部分的知识的重大改进。改进后的质量可以为恒星结构和演化计算以及与观测结果的比较提供必要的约束。* * *
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. ***
