“This matematical model of giant convection cells on the sun’s surface are giving scientists an unprecedented view of the solar interior thanks to a new model powered using the Teragrid supercomputer. To map the giant cells, NCAR and UCAR scientists drew on data from helioseismology—a technique to measure sound waves that propagate deep within the interior of the Sun—and used Teragrid resources to solve the equations of stellar fluid dynamics. By analyzing variations in the light and velocity of the waves as they emerge on the Sun’s surface, scientists can glean information about hidden subsurface structures.”
