  Appl Math: Richard Townsend on "Numerical Asteroseismology with the GYRE Code"

  McCormick-Engineering Sciences and Applied Mathematics (ESAM)

  11:15 AM M416, Technological Institute

  EVENT DETAILS

  Title: Numerical Asteroseismology with the GYRE Code

  Speaker: Richard 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.

  Appl Math: Roberto Zenit on "The Fluid Mechanics of Splatter Painting"

  McCormick-Engineering Sciences and Applied Mathematics (ESAM)

  11:15 AM M416, Technological Institute

  EVENT DETAILS

  Title: The Fluid Mechanics of Splatter Painting

  Speaker: Roberto Zenit, Brown University

  Abstract: In splat painting, a collection of liquid droplets is projected onto the substrate by imposing a controlled acceleration to a paint-loaded brush.

  To unravel the physical phenomena at play in this artistic technique, we perform experiments where the amount of expelled liquid is characterized function of the liquid viscosity, brush properties and imposed acceleration. Experimental trends are rationalized by simple physical models, revealing the existence of an inertia-dominated flow in the anisotropic, porous tip of the brush. We argue that splat painting artists intuitively tune their technique to work in this regime, which may also play a role in other pulsed flows, like fabric drying, violent expiratory events or sudden geophysical processes.
