First announcement: Dynamics of the Sun & stars – Michael Thompson in memoriam

April 8, 2019, from Jørgen Christensen-Dalsgaard

Dynamics of the Sun & stars; Honoring the life and work of Michael Thompson

24 – 26 September 2019, High Altitude Observatory, Boulder, Colorado

This meeting celebrates Michael Thompson’s seminal work on solar and stellar physics, as well as his major contributions to the development of the National Center for Atmospheric Research, and marks his untimely death in October 2018. Michael played a key role in the development of helioseismology and its application to the study of the structure and dynamics of the solar interior, and he provided a strong foundation for the extension of seismic studies to other stars. After concentrating for several years on more administrative activities he was returning to leading the seismic studies of solar interior rotation and he was deeply involved in the understanding of the dynamics of the core of stars, when his life was tragically lost.

The conference will focus on dynamical aspects of the sun and stars, based on the large amount data available on solar and stellar oscillations, and the extensive and detailed modelling now becoming feasible. By combining observations, seismic analysis and modelling we hope that this will be a fitting memorial for a close colleague and friend, much missed.
