COLLOQUIUM 2024

Abstract

For centuries, the interiors of stars have been thought impossible to probe. Only in the past three decades has asteroseismology, the study of stellar oscillations, allowed us to peer through stellar atmospheres and probe the insides of stars. It is therefore the only method that allows the determination of a star’s mass, radius, and age based on its interior properties. I will discuss how we measure the vibrations of stars like our Sun and what we can learn about the lifetimes of such stars. Asteroseismology is emerging as a powerful tool in modern astronomy for studying the history of our Galaxy and for revealing new discoveries about planets outside our Solar System. This is now made possible by our ability to survey millions of stars across the sky from NASA’s space telescopes, as well as the growing influence of machine learning and AI in astronomy. I will showcase discoveries in Galactic archaeology and exoplanetary science, along with exploring the potential of AI in the survey era of asteroseismology.
