Using the sounds of stars to reveal the Milky Way's evolution

点击翻译按钮获取中文摘要

This project aims to use a completely new approach to investigate how our Galaxy formed and evolved, by merging two fields within astrophysics – galactic archaeology and the study of stellar oscillations. This will dramatically improve understandings of the fundamental physics that governs the evolution of all cool stars, such as the Sun. This project aims to go beyond classical astronomy, which examines only the surface of stars. For the first time, the interior structure of thousands of stars across the Galaxy will be probed to reveal intricate details of its evolution from the imprint of each star's oscillations. This will be possible through access to data of extremely high precision from one European and two National Aeronautics and Space Administration (NASA) space telescopes.
