Hearing the Stars: New Insights into Stellar Interiors

Space-based observations have provided a remarkable new tool for studying stars within our galaxy, the Milky Way. Simply by measuring how bright a star is over many years, we can now directly measure its mass and radius, as well as the properties of its deep interior, such as the rate of rotation. This has been done for tens of thousands of stars across the Milky Way, also allowing us to unravel how the galaxy was formed over cosmic time. It's a great story of how theory and observation, together, can make a remarkable impact on our understanding of the universe.
