Research on Infrared Imaging with IOTA

AST-0138303Schloerb，F.Peter三望远镜IOTA，迈克尔逊恒星干涉仪的灵敏度将通过增加新的高速可见光尖端/倾斜跟踪器、单模红外光纤和改进的红外尖端/倾斜跟踪器来提高，这些追踪器将用于观测用可见光传感器无法跟踪的高度变红的物体。这些改进将把科学测量的天文等限值从目前的7.5等限值(R波段)扩大到9.0等限值(R波段)。这一新系统将使研究赫比格Ae/Be恒星和T金牛座恒星光球表面特征和质量交换相互作用成为可能。。***

AST-0138303Schloerb, F. PeterThe sensitivity of the three-telescope IOTA, a Michelson Stellar Interferometer will be improved through the addition of a new high speed visible light tip/tilt tracker, single-mode IR fiber optics, and an improved IR tip/tilt tracker, which will be used to observe highly reddened objects that are untrackable with the visible sensor. These improvements will extend the limiting astronomical magnitude for science measurements from the current 7.5 magnitude limit (R-band) to a 9.0 magnitude limit (R-band). This new system will enable studies of surface features and mass exchange interactions across the surface of the photospheres of Herbig Ae/Be stars and T Tauri stars. . ***
