VERITAS成像空气切伦科夫望远镜（IACT）阵列于2019年通过高速焦平面电子设备进行了增强，使其能够用于恒星强度干涉测量（SII）观测。自2019年1月以来，VERITAS恒星干涉仪（VSII）在416 nm的有效光波长下对39颗不同的明亮恒星和双星系统（mV < 3.74）进行了超过250小时的月光观测。这些观测结果测量了几颗恒星的直径，分辨率超过5%。本次演讲将描述VSII调查和分析的现状。
The VERITAS Imaging Air Cherenkov Telescope (IACT) array was augmented in 2019 with highspeed focal plane electronics to allow its use for Stellar Intensity Interferometry (SII) observations. Since January 2019, The VERITAS Stellar Interferometer (VSII) recorded more than 250 hours of moonlit observations on 39 different bright stars and binary systems (mV < 3.74 ) at an effective optical wavelength of 416 nm. These observations resulted in the measurement of the diameters of several stars with better than 5% resolution. This talk will describe the status of the VSII survey and analysis.
