Seismology of the Sun
Seismology of the SunTuesday 11th April 2017
Social gathering starts at 5:00PM
Presentation starts at 5:30PM
The Sun vibrates in millions of modes of acoustic oscillation, continuously excited by convection in the near-surface layers. These oscillations enable astrophysicists to `see’ inside the Sun in three dimensions, in much the same way as exploration geophysicists probe the subsurface of the Earth with seismic waves. Ongoing helioseismic observations by the Solar Dynamics Observatory, a NASA spacecraft, have led to renewed efforts to determine the plasma flows in the solar interior that are thought to drive solar magnetic activity. In this presentation I will mention the need for new accurate techniques of forward and inverse modeling in order to realize the full potential of helioseismology, and emphasize some of the synergies with exploration geophysics. .
Laurent Gizon has been a co-principal investigator and a research professor at the Center for Space Science, NYUAD Institute since 2015. From 2011 he is a director at the Max Planck Institute for Solar System Research and a Professor of Physics at the University of Goettingen, Germany. His research is focused on the internal structure and dynamics of the Sun and Sun-like stars. Laurent holds a PhD in physics from Stanford University .
