Using asteroseismology, scientists can analyze stars' intrinsic pulsations to tease out the physical properties of stellar interiors. Now scientists have applied asteroseismology to unmask a white dwarf—a star in the slow cooling phase that marks the end of the life cycle of all but the most massive stars. The results confirm the broad contours of stellar evolution theory but significantly challenge the particulars.
