ASTRONOMY COLLOQUIUM

Stars play an important role in astrophysics as exoplanet hosts, progenitors of supernova & compact objects, and as a source of chemical enrichment. The advent of high-precision photometric observations of stars has enabled asteroseismology to probe the interiors of stars better than ever before. Although stellar structure and evolution are typically studied using one-dimensional models, new asteroseismic observations have yielded new mysteries, indicating the presence of poorly-understood multidimensional processes. Many of these processes also occur on the Earth & other planets. In this talk, I will use laboratory experiments and numerical simulations with the open-source Dedalus code to better understand multidimensional processes important in stars and planets. Combining insights from different fields is key to making predictive and accurate models of stars that are so important across astrophysics.
