PAMS Seminar: "Seismology of the Sun and Stars" by Dr. Jason Jackiewicz

Abstract:
For over 100 years, Earth seismologists have been compiling a detailed understanding of our planet’s interior from earthquake data and theoretical modeling. When oscillations in the Sun were first observed about 50 years ago, solar seismologists were in the fortunate position to “adopt” the tools geoseismologists had developed to peer inside our nearest star. Only within the past 10 years, seismology of distant pulsating stars has become possible, and very powerful. The coming decade holds promise for exploiting oscillations of giant planets to probe their (currently unknown) internal structure.
     Seismology of these distinct objects is in principle equivalent: it comprises a set of tools to measure and interpret oscillation data with the aim of making inferences of sub-surface structure and dynamics at the highest spatial and temporal resolution possible. This talk will discuss the techniques (measurements, modeling, inversions, etc.) that seismologists employ, and present some exciting results in the context of solar/stellar structure and evolution that make this an era of precision astrophysics.
