Study of Star Forming Regions and Compact Objects by International Cooperative Observations of Radio and Infrated Radiation

1.本项目的目的是通过将野边山射电天文台的毫米波望远镜与世界顶级仪器联合收割机相结合的系统合作观测，揭示星际物质、星星和行星的形成、星系核等。在该基金资助的3年内，87名天文学家被派往海外观测55个项目。这些计划包括世界上大多数主要望远镜的观测：UKIRT，JCMT，FCRAO，VLA，Kitt Peak，Cero，Tololo，CEST，Parkes等。17个项目是VLBI，其中包括一些涉及网络中的Nobeyama 45米望远镜的观测。10个项目用于数据处理和仪器开发的国际合作。项目成果通过该项目获得的科学成果发表在下面列出的62篇论文（英文）中。最近的观测结果也在审查专题讨论会上报告， 关于我们 其诉讼程序正在印刷中。通过各种观测，对星际物质到恒星和行星系统的过程有了系统的了解。个别研究的一些例子如下。(1)探测到星星形成区氢分子的荧光红外线（长谷川，田中等人）。(2)通过红外散斑干涉测量法（Maihara，Kataza等人）在金牛座T星中探测到许多近距离双星系统。(3)用亚毫米观测揭示了原恒星周围尘埃盘的结构（Yamashita，Kaifu等人）。(4)在星星形成区探测到新的水汽脉泽源（龟谷等人）。(5)通过广泛的毫米波调查揭示了猎户座巨型分子云的宽场结构和云核的统计数据（Tatematsu，Umemoto等人），和许多其他人。对日本天文学的影响Noveyama毫米波望远镜带来了突破，不仅在日本毫米波天文学的顶级数据上，而且在与世界顶级仪器的平等合作上。该项目将许多年轻的天文学家送到观测天文学的活跃中心，并成功地将观测天文学和仪器发展的高活动带到了日本的亚毫米，红外和光学天文学。少

1. Status of Project This project aims to reveal interstellar matter, star and planet formation, and galactic nucleus etc. by systematic cooperative observations which combine the millimeter-wave telescopes of Nobeyama Radio Observatory and the world top-class instruments. Within 3 years supported by this grant, 87 astronomers were sent for 55 programs in the overseas observatries. The programs include the observations with most of the world principal telescopes : UKIRT, JCMT, FCRAO, VLA, Kitt Peak, Cero, Tololo, CEST, Parkes, and others. 17 programs were for VLBI, among them included a number of observations involved the Nobeyama 45-m telescope in the network. 10 programs were for the data reduction and for the intrnationa collaboration on the instrumental developments.2. Results of Project The scientific results obtained through this project were published in the 62 papers (in English) listed below. Also the results from recent observations were reported in the review symposium, the … More proceedings of which are in press. A systematic understandings of the process from interstellar matter to stars and to planetary systems were improved in great deal throngh various observations. Some examples of individual studies are as follows. (1) Detected fluorescent infrared lines of molecular hydrogen in star forming regions (Hasegawa, Tanaka, et al.). (2) Detected many close binary systems among T-Tauri stars by means of the infrared speckle intrferometry (Maihara, Kataza et al.). (3) Revealed the structure of dust disks around proto-stars with the sub-mm observations (Yamashita, Kaifu et al.). (4) Detected new water vapor maser sources in star forming regions (Kameya et al.). (5) Revealed the wide-field structure of Orion giant molecular cloud and statistics of cloud cores by extensive mm-wave survey (Tatematsu, Umemoto et al.), and many others.3. Impact to the Japanese Astronomy The Noveyama mm-wave telescopes have brought a breakthrough, not only on the top-level data in mm-wave astronomy in Japan but also on the equal-based collaboration with the world top-class instruments. This project sent many young astronomers to active centers of observational astronomy, and as the results high activities on the observational astronomy and instrumental developments were brought to Japanese sub-mm, IR and optical astronomy, successfully.
