  text: Asteroseismology is the study of the interior physics and structure of stars
    using their pulsations. It is applicable to stars across the Hertzsprung–Russell
    (HR) diagram and a powerful technique not only to measure masses, radii, and ages
    but also directly constrain interior rotation, chemical mixing, and magnetism.
    This is because a star's self-excited pulsation modes are sensitive to its structure.
    Asteroseismology generally requires long-duration and high-precision time-series
    data. The method of forward asteroseismic modeling, which is the statistical comparison
    of observed pulsation mode frequencies to theoretically predicted pulsation frequencies
    calculated from a grid of models, provides precise constraints for calibrating
    various transport phenomena. In this introduction to asteroseismology, we provide
    an overview of its principles, and the typical data sets and methodologies used
    to constrain stellar interiors. Finally, we present key highlights of asteroseismic
    results from across the HR diagram, and conclude with ongoing challenges and future
    prospects for this ever-expanding field within stellar astrophysics.
