Study of Solar Oscillations Phase I, Site Evaluation, Award in U.S. and Indian Currencies

描述：这笔拨款为亚利桑那州图森国家太阳天文台（NSO）的John W. Leibacher博士领导的一个美国小组和印度乌代普尔太阳天文台（USO）主任a. Bhatnagar博士领导的一个印度小组的联合研究提供支持。该研究的第一阶段将包括对乌代浦尔作为全球振荡网络集团（GONG）项目六个站点之一的站点进行评估。GONG项目旨在通过在地球表面不同地点观测太阳（离地球最近的恒星）表面的振荡来获取信息。研究太阳振荡的日震学已经发展成为一种新的强有力的工具，它可以相当精确地探测太阳内部，就像地面地震学揭示地球内部的信息一样。由于第二阶段将使用的仪器和观测计划相当敏感和复杂，因此在全球考虑的各个地点进行某些评估实验是很重要的，包括乌代普尔地点，在做出最后的六个地点的选择之前。范围：印度科学家对太阳物理学领域做出了重大贡献。USO有一个独特的地理位置，它位于一个大气相当清澈的地区，在全球范围内与位于图森的国家气象局的位置大致相反。印度政府的支持对实验的成功至关重要。这笔赠款将使美国小组能够进行必要的初步测试，并与印度政府谈判从不同政府机构获得所需的设施。资助：本项目获以下两项拨款资助：FY国家太阳观测台乌代普尔太阳观测台__ __________________________ ___________________美元印度货币美元印度货币90 1,130 5,843 20,588 91 2,260 24,933 18,823

Description: This grant provides support for a joint research by a U.S. team headed by Dr. John W. Leibacher of the National Solar Observatory (NSO) in Tucson, AZ, and an Indian team headed by Dr. A. Bhatnagar, Director of the Udaipur Solar Observatory (USO) in Udaipur, India. The research, in its first phase, will cover site evaluation of Udaipur as one of six sites for the Global Oscillation Network Group (GONG) project. The GONG project seeks to obtain information through observations, made at different sites on the surface of the earth, of the oscillations at the surface of the sun, the earth's nearest star. Helioseismology, the study of these solar oscillations, has been developed as a new powerful tool that can probe the solar interior with considerable precision much in the same way that terrestial seismology reveals information about the interior of the earth. Because the instruments and the program of observation to be used during the second phase are quite sensitive and complicated, it is important to run certain evaluative experiments on the various sites under consideration around the globe, including the Udaipur site, before making the final selection of the six sites. Scope: Indian scientists have contributed significantly to the field of solar physics. The USO has a unique geographical location being in an area of considerable atmospheric clarity and at approximately opposite position around the globe to the NSO in Tucson. The support of the Government of India (GOI) will be crucial for the success of the experiments. This grant will enable the U.S. team to conduct the necessary preliminary tests and to negotiate with the GOI the required facilities from different governmental agencies.
