lessTitle: Numerical Asteroseismology with the GYRE Code
Speaker: Rich Townsend, University of Wisconsin
Abstract: Some stars display periodic fluctuations in their brightness, arising from the excitation of their global oscillation modes. By modeling these fluctuations, we can place remarkably narrow constraints on the stars' global properties and detailed internal structure—a technique known as "asteroseismology".
In this talk I'll review the theoretical principles of asteroseismology, and describe their implementation in GYRE—an open-source code I've been developing for a little over a decade. Despite committing a fair number of computational cardinal sins, GYRE appears to be accurate, robust, and fast, and has been adopted by many groups around the world as their workhorse for numerical asteroseismology. I'll showcase a few GYRE-based projects that I've recently been involved in, and then discuss enhancements that enable GYRE to simulate tidal phenomena in binary-star and star-planet systems.
