标题： Star and Cluster Formation in the Large Magellanic Cloud

摘要： 一个巨大的星团形成爆发使大麦哲伦星云在3-5 Gyr前开放星团的形成速率至少提高了一个数量级。 另一方面，约4 Gyr前的恒星形成速率似乎仅增加了2-4倍。 这表明星团形成速率并不是恒星形成速率的良好指示器。 在相同的恒星形成速率下，目前大麦哲伦星云形成的星团数量是本地集团矮不规则星系IC 1613的600倍。 合并的富气体星系中较高的星团形成速率表明，强烈的激波可能有助于星团的形成。 显示英文摘要

摘要： A great burst of cluster formation increased the rate at which open clusters were formed in the Large Magellanic Cloud 3-5 Gyr ago by at least an order of magnitude. On the other hand the rate of star formation ~ 4 Gyr appears to have increased by a factor of only 2-4. This shows that the rate of cluster formation is not a good tracer of the rate at which stars are formed. Normalized to the same rate of star formation, the Large Cloud is presently forming / 600 times more star clusters than the Local Group dwarf irregular IC 1613. The high rate of cluster formation in merging gas-rich galaxies suggests that strong shocks might favor the formation of clusters.
