Dr K.R. Sreenivasan on our shuddering sun
Dr K.R. Sreenivasan of the NYU Polytechnic School of Engineering today presented on solar turbulence and helioseismology in the fascinating NYU Abu Dhabi public talk "Tempest in the Sun". I got in quite late because of crash traffic along the way, but I arrived by the time he started talking about deep convection and Erika Böhm-Vitense's mixed length theory. He then explained his work on using observations of ripples bouncing around the solar mass to peer into the sun's internal dynamics, and how differences in the expecting timing of waves indicate the underlying flow rate in the photo-opaque, but acoustically resonant sun.
