Learning stellar physics and unravelling history of the Milky Way using asteroseismology

Recent developments in the seismology of stars have led to a revolution in stellar physics. The available high-fidelity seismic data from past (CoRoT and Kepler/K2) and present (TESS) space missions provide unparalleled opportunity to investigate and resolve the shortcomings of models of stellar structure and evolution. Moreover, precision measurements of the spectroscopic and seismic observables enable us to infer stellar parameters such as mass, radius and age to unprecedented accuracy for a large sample of stars, paving the way for studying properties of exoplanets and unravelling history of the Milky Way. In this talk, I shall give examples of studying both, stellar physics and Galactic chemical evolution, using asteroseismology. Particularly, I shall focus on the signatures of acoustic glitches for stellar physics and seismically measured stellar ages for Galactic study.
