White dwarf stars are the endpoints of most stellar evolution, and these compact objects enable us to study the physics of matter under extreme conditions. Pulsating white dwarf stars ring out in multiple simultaneous frequencies that can, in principle, be used to sensitively map the stellar interior—a technique known as asteroseismology. The availability of high-speed precision photometry from the space missions Kepler and TESS has revolutionized our understanding of white dwarf pulsations over the past decade. More recently, Gaia has provided synergistic astrometry data that can aid asteroseismic analyses. I will summarize our modern understanding of white dwarf pulsations, and I will share my vision for how astrometry data and pulsation data can be brought together to realize the full potential of white dwarf asteroseismology.
