Compute Canada’s Newest Supercomputer Niagara Simulates Life of a Star

WestGrid user and University of Victoria researcher Falk Herwig and his collaborators have used Compute Canada Niagara supercomputer to simulate life of a star. A summary of their work was recently profiled in R&D magazine

To understand a star’s structure, researchers simulate them on a supercomputer using complex hydrodynamics calculations over a long series of time steps. These very detailed simulations of the core convection in a massive star reveal the turbulent flows of the interior and stellar oscillations that can be observed with space telescopes like Kepler or TESS. These simulations provide exquisite detail on how different parts of the stars are mixed, which in turn improves our understanding how the elements form in stars and stellar explosions. Read the full article here.
