项目摘要

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.

一、项目概况本项目旨在通过野边山射电天文台毫米波望远镜与世界一流仪器相结合的系统性合作观测，揭示星际物质、恒星和行星的形成、银核等。在这笔资助的支持下，三年内，87名天文学家被派往海外天文台执行55个项目。这些计划包括使用世界上大多数主要望远镜进行的观测：UKIRT、JCMT、FCRAO、VLA、Kitt Peak、Cero、Tololo、CEST、Parkes 等。 VLBI 项目有 17 个，其中包括一些涉及网络中野边山 45 米望远镜的观测。 10 个项目用于数据缩减和仪器开发方面的国际合作。2．项目成果通过该项目获得的科学成果发表在下列 62 篇论文（英文）中。最近的观察结果也在审查研讨会上报告，会议记录正在印刷中。通过各种观测，对从星际物质到恒星再到行星系统的过程的系统理解得到了很大的提高。个别研究的一些例子如下。 (1) 在恒星形成区域检测到分子氢的荧光红外线（Hasekawa、Tanaka 等人）。 (2) 利用红外散斑干涉测量法在T-Tauri星中探测到许多邻近的双星系统(Maihara, Kataza等)。 (3) 通过亚毫米观测揭示了原恒星周围尘埃盘的结构（Yamashita、Kaifu等）。 (4) 在恒星形成区域检测到新的水蒸气脉泽源（Kameya 等人）。 (5) 通过广泛的毫米波巡天(Tatematsu, Umemoto等)等揭示了猎户座巨分子云的宽场结构和云核的统计数据。3．对日本天文学的影响 Noveyama毫米波望远镜不仅在日本毫米波天文学的顶级数据上带来了突破，而且在与世界顶级仪器的平等合作上也取得了突破。该项目将许多年轻的天文学家派往活跃的观测天文学中心，结果，观测天文学和仪器开发的高度活动成功地引入了日本亚毫米、红外和光学天文学。较少的
