GYRE is a stellar oscillation code. Given an input stellar model, GYRE calculates the eigenfrequencies and eigenfunctions for the normal oscillation modes of the model. These data can be put to a variety of uses; the most common is to compare them against observed oscillation frequencies of a star, allowing constraints on the star's fundamental parameters (mass, radius, etc.) to be established — the discipline of asteroseismology.
