Microlensing Observations in Astrophysics in NZ

MOA(天体物理学中的微透镜观测)日本-新西兰天文学观测小组MACHO被称为MOA，这是一只新西兰的大鸟，正在坎特伯雷大学约翰山天文台为MACO准备1995年的观测。MOA的目标是在银晕中寻找行星质量的马霍星(太阳质量的0.1)，具体如下：1.天文台：约翰大学天文台，坎特伯雷，新西兰44号，东经170度，1000平方米。望远镜：改进型Boller&Chivens，D=0.6米，1.4度视场，计算机控制全天跟踪和回转。摄像头：1996年：900万像素，T1215-T，0.65弧秒1997：1600万像素，SLTe-002，0.81弧秒，背面采用AR涂层照明。天空覆盖(1996)：LMC酒吧和周围地区，1.1*3.3度，每晚最多5次4分钟的红色和蓝色曝光。MOA从1996年3月才开始观测。MOA得到了新西兰马斯登基金和日本文部省国际科学研究计划和补助科学研究计划的支持。

MOA (Microlensing Observations in Astrophysics)The Japan-NZ Macho Observation team for Astronomy called MOA,a big bird in New Zealand, is preparing observation for Macho at Mt.John observatory of the University of Canterbury in 1995. MOA aims to search for planet mass machos (<0.1 of solar mass) in the halo of the Galaxy as follows :1. Observatory :Mt.John University Observatory, Canterbury, NZ 44S,170E,1000m2. Telescope : modified Boller & Chivens, D=0.6m, 1.4 degree field, computer controlled tracking and slewing over whole sky.3. Camera : 1996 : 9 million pixels, Tl215-T,0.65arc secs 1997 : 16 million pixels, SlTe-002,0.81 arc secs, back side illuminated with AR-coating.4. Sky coverage (1996) : LMC bar and environs, 1.1*3.3 degrees, up to five 4 minute red and blue exposures per night.MOA has started the observation just from March 1996.MOA is supported by the Marsden Fund of NZ and the International Scientific Research porgram and A Grant-in Aid for Scientific Reserach Program of the Ministery of Education of Japan.
