报告摘要：

～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

Eclipsing binary stars are the cornerstone of stellar astrophysics. The models of eclipsing binary observables yield the most accurate fundamental parameters (masses, radii, temperatures and luminosities) for the system components. Yet to model observations of a single binary star, it takes time. Depending on the number of data points, a typical forward model (synthesizing observables from passed parameters) can take minutes or longer. While that might not sound like much, when sampling the parameter space, we need millions of forward model computations. In this talk I will introduce the eclipsing binary model PHOEBE and show how artificial intelligence can reduce the time cost by whopping 7 orders of magnitude.
