EARTH AND STARS

Seismology of the Earth and Stars
May 4-6, 2011

Program Organizers: Shravan Hanasoge, Yang, Luo & Jeroen Tromp

The idea of using waves to probe the optically invisible interiors of objects has proven to be highly successful in determining the structure of widely different media such as earth, Sun, and with the advent of astro-seismology, a vast spectrum of stars. Despite the disparate paths these fields have taken, exacerbated by the few opportunities for interdisciplinary conference, a surprising degree of unity in the ideas and techniques still persists. In particular, the direct analogy between ambient noise tomography of the earth and helioseismology has allowed the development of mutually beneficial ideas. In light of recent progress in these areas, the proposed workshops are not only timely but may lead to the emergence of novel ideas and new collaborations.

Differential Rotation in Stars
May 9-13, 2011

Program Organizers: Steven Balbus, Mark Miesch, James Stone, Nigel Weiss

The importance of understanding how and why stars acquire differential rotation manifests itself in many ways.  The convergence of helioseismology results of the space-based Solar and Heliospheric Observatory (SOHO) and terrestrial Global Oscillation Network Group (GONG) has provided hydrodynamicists with a unique oppportunity: the internal rotation velocity of a turbulent, spinning fluid is now known with great accuracy.  In this multi-disciplinary meeting, observers, numericists, and theorists will be brought together for intense discussion and the generation of new ideas.
