How Old Are The Stars? Looking Inside Stars with Asteroseismology

恒星是宇宙的基石。了解它们的结构和演化是现代天体物理学的基础，从描述越来越多的太阳系外行星到揭开我们银河系的历史。这个研究项目将使用星震学技术，即研究星震的技术，以非常详细的方式探测恒星的内部，并以前所未有的精度测量它们的年龄。获得大量恒星的准确年龄将有助于我们了解银河系是如何形成和发展的。我们将深入了解恒星内部发生的过程，指导新一代研究人员，并使澳大利亚成为恒星天体物理学的世界领导者。

Stars are the building blocks of the Universe. Understanding their structure and evolution underpins much of modern astrophysics, from characterising the growing number of extra-solar planets to unravelling the history of our Milky Way Galaxy. This research program will use the technique of asteroseismology, the study of starquakes, to probe the interiors of stars in extraordinary detail and measure their ages with unprecedented precision. Having accurate ages for large numbers of stars will help us understand how the Milky Way galaxy formed and developed. We will generate a deep understanding of the processes that occur inside stars, mentor a new generation of researchers and establish Australia as a world leader in stellar astrophysics.
