The Formation, Evolution and Age of the Heavy Elements

9314936科万我们银河系的历史部分地通过不同年龄恒星的组成来揭示。 天文仪器和恒星光谱分析的最新发展大大增加了关于恒星组成的可用信息。 PI将利用这些新信息来确定重元素形成所需的条件。 然后，他将追溯整个银河系的历史。 由此产生的星系化学演化模型将允许重新确定重元素的年龄。 ***

9314936 Cowan The history of our galaxy is revealed in part by the compositions of stars of various ages. Recent developments in astronomical instrumentation and in the analysis of stellar spectra have greatly increased the available information on stellar compositions. The PI will take advantage of this new information to determine the conditions required for the formation of heavy elements. He will then trace element generation throughout the history of the Galaxy. The resulting model for the chemical evolution of the galaxy will allow a new determination of the age of the heavy elements. ***
