Using the TeraGrid to Understand the Stars and Search for Planets: Problem: The oscillations modes of stars give clues to the stellar interior. Accurate modeling of these oscillations can tell us the size, composition and age of stars, and in turn help interpret the data returned by NASA’s Kepler Mission in the hunt for Earth-like extrasolar planets. Solution: NCAR is working with the international science community to develop a TeraGrid science gateway to fit oscillation data with stellar models to determine these parameters automatically for large numbers of stars. Key Elements: international science impact, gateway technology. 1/20/2016 The turbulent solar atmosphere captured with NASA’s TRACE satellite is overlaid with a model of one of the millions of oscillation modes that allow scientists to deduce the Sun’s hidden internal structure and dynamics. Similar measurements are now being made for other solar-type stars.
