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.

1。项目的状态该项目旨在通过系统的合作观察（结合了Nobeyama无线电天文台和世界顶级仪器的毫米波望远镜）来揭示星际物质，星形和星球的形成以及银河核心等。在这笔赠款支持的3年内，有87名天文学家在海外观察中获得了55个计划。这些计划包括与世界大多数主要望远镜的观察：UKIRT，JCMT，FCRAO，VLA，KITT PEAK，CERO，CERO，TOLOLO，CEST，CEST，PARKS等。 VLBI有17个计划，其中包括许多观察结果，其中涉及Nobeyama 45-M望远镜。有10个计划减少数据和该国在工具开发方面的合作。2。项目的结果通过该项目获得的科学结果发表在下面列出的62篇论文（英文）中。同样，在审查研讨会上报道了最近观察结果的结果，其中更多的会议记录在印刷中。从星际物质到恒星到行星系统的过程有系统的理解，对许多不同的观察得到了很大的改进。单个研究的一些例子如下。（1）在恒星形成区域中检测到的分子氢的荧光红外线（田中，田中等）。（2）通过红外斑点秘密仪（Maihara，Kataza等人）检测到T-Tauri恒星之间的许多近距离系统。（3）揭示了带有亚MM观测的原始明星周围尘埃的结构（Yamashita，Kaifu等人）。（4）检测到恒星形成区域中的新水蒸气Maser源（Kameya等人）。（5）揭示了通过广泛的MM波调查（Tatematsu，Umemoto等）和许多其他猎户座巨型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 MM-Wave望远镜不仅在日本的MM-Wave天文学中的顶级数据上都带来了突破，而且在与世界顶级工具的基于平等的合作中。该项目将许多年轻的天文学家送往观察天文学的活跃中心，并且随着对观察性天文学和工具发展的最高活动的成功，已成功地向日本的Sub-MM，IR和光学天文学带来了成功。较少的
