SPD Hale Lecture: Tom Duvall

Thomas L. Duvall (NASA Goddard Space Flight Center) received the George Ellery Hale Prize from the Solar Physics Division (SPD) "for his invention and application of innovative helioseismic methods and the resulting ground-breaking discoveries within the solar interior, including internal sound-speed and rotation profiles, meridional circulation, wave perturbations in sunspots, and large-scale convection properties." After being introduced by SPD chair Leon Golub (Smithsonian Astrophysical Observatory), Duvall gave his prize lecture entitled "Waves Excited by Noise: Applications to Helioseismology and Beyond."
