悉尼大学的热星干涉测量研究
Interferometric Studies of Hot Stars at Sydney University
摘要：
悉尼大学在光学恒星干涉测量方面有着悠久的历史。第一个项目是在1960年代的Narrabri恒星强度干涉仪，它测量了32颗热恒星的角直径，并建立了光谱类别O - F的温标。该仪器之后是悉尼大学恒星干涉仪（SUSI），目前正在进行第三代升级，以使用多波长PAVO光束组合器。SUSI在可见光而不是红外波长下工作，基线可达160米，因此非常适合研究热星。已经进行了一些研究，并计划在PAVO系统调试完成后进行更多的研究。将该系统转换为远程操作将使更大的科学项目得以开展。
英文摘要：
The University of Sydney has a long history in optical stellar interferometry. The first project, in the 1960s, was the Narrabri Stellar Intensity Interferometer, which measured the angular diameters of 32 hot stars and established the temperature scale for spectral classes O - F. That instrument was followed by the Sydney University Stellar Interferometer (SUSI), which is now undergoing a third-generation upgrade, to use the multi-wavelength PAVO beam combiner. SUSI operates at visible rather than IR wavelengths and has baselines up to 160 m, so it is well suited to the study of hot stars. A number of studies have been carried out, and more are planned when commissioning of the PAVO system is complete. Conversion of the system to allow remote operation will allow larger scientific projects to be undertaken.
