  • IAU是世界天文学的大家庭。1935年中国正式加入IAU,成为了继前苏联之后IAU第26个的团体会员。1960年,由于政治原因中国暂时退出。1982年,IAU第18届大会通过决议,“中国”名下设两个正式会员,名称分别为“中国天文学会”和“位于中国台北的天文学会”,注册地点分别为中国南京和中国台湾台北。近年来,中国天文学和中国天文学家在国际大家庭中的声音和影响越来越大。   叶先生的中国高度 叶叔华院士1988-1994年曾担任国际天文学联合会副主席。这次,年逾九旬的叶先生又亲临IAU大会现场,据说是最高龄的参会者。叶先生不仅参加会议,她还带来了自己最新的科学设想 ...
  • 2017年12月31日,包含先导巡天及正式巡天前五年观测数据的LAMOST DR5数据集正式发布,供国内天文学家和国际合作者使用。
    LAMOST DR5的天区覆盖图,不同颜色代表不同观测年度   LAMOST DR5包括先导巡天及一期五年正式巡天4154个观测天区中逾9百万条光谱,其中高质量光谱数(S/N>10)超过750万条 ...
    另外,发布数据中还包括了5百万颗A、F、G、K型恒星参数表,50万颗M型矮星参数表等。LAMOST再一次以“实际行动”证明了其光谱获取率世界第一的能力。
