Our understanding of the formation and evolution of the Milky Way and galaxies is often blurred and biased by the lack of precise and accurate stellar ages. Asteroseismology, i.e., the study of global, resonant oscillation modes in stars, is providing us with a formidable tool to unveil detailed insights into the internal structure of stars, paving the path for robust age determinations.
In this presentation I will discuss the ongoing efforts and recent results of the asterochronometry project, which aims to test our knowledge of stellar physics while providing precise and accurate age estimates (within 10-20%) for stars in the regions of the Galaxy surveyed by the space telescopes Kepler, K2, CoRoT, and TESS.
While I will showcase examples of asteroseismology's role in reconstructing the early assembly history of the Milky Way, I will also highlight the limitations we encounter emphasising that these hurdles can only be truly overcome via an improved understanding of stellar physics.
Finally, I will discuss the prospects for extending these studies to larger samples, and outline the scientific rationale for a future space mission dedicated to asteroseismology in “controlled environments”. Such a mission would transform stars into laboratories, enabling us to test stellar physics catalysing the development of next-generation stellar models.

SPEAKER: Andrea Miglio (University of Bologna)
We are glad to invite you to the next Rome Joint Astrophysics Colloquium (JAC) on Wednesday the 14th of February at 14:30 CEST.
The Rome JAC is a joint initiative of the Physics Dept. of the Tor Vergata University of Rome, INAF - Astronomical Observatory of Rome, and INAF - Institute for Space Astrophysics and Planetology.
The talk will be held in a hybrid format allowing both virtual (through the link below) and in-person attendance (Aula Gratton, Astronomical Observatory of Rome).
