VERITAS成像空中切伦科夫望远镜阵列(IACT)于2019年通过高速焦平面电子设备进行了增强,以创建新的恒星强度干涉测量(SII)观测能力(VERITAS-SII,或VSII)。VSII在明月期运行,利用望远镜空闲时间在B波段提供高角分辨率观测(< 1 mas)。VSII已经展示了使用相对较短(5小时)的曝光,以小于5%的精度测量两颗B星在416 nm (betcma和Eps Ori)的直径的能力。VSII仪器最近进行了改进,以提高仪器灵敏度和观测效率。本文介绍了升级后的VSII仪器,并记录了VSII灵敏度的持续改进。该报告描述了VSII在将SII测量扩展到较暗恒星以及将VSII角直径测量分辨率提高到1%以上方面的进展。
The VERITAS Imaging Air Cherenkov Telescope array (IACT) was augmented in 2019 with high-speed focal plane electronics to create a new Stellar Intensity Interferometry (SII) observational capability (VERITAS-SII, or VSII). VSII operates during bright moon periods, providing high angular resolution observations ( < 1 mas) in the B photometric band using idle telescope time. VSII has already demonstrated the ability to measure the diameters of two B stars at 416 nm (Bet CMa and Eps Ori) with < 5% accuracy using relatively short (5 hours) exposures.1The VSII instrumentation was recently improved to increase instrumental sensitivity and observational efficiency. This paper describes the upgraded VSII instrumentation and documents the ongoing improvements in VSII sensitivity. The report describes VSII’s progress in extending SII measurements to dimmer magnitude stars and improving the VSII angular diameter measurement resolution to better than 1%.
