R&D magazine report on our core convection hydrodynamics simulations on the new Canadian Niagara supercomputer

As R&D magazine reports Herwig and his collaborators have used "Canada’s most powerful research supercomputer to simulate life of a star”. 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.

Stellar Hydrodynamics

Together with Paul Woodward and his group we are investigating stellar interior convection with nuclear burning at Damköhler numbers ~1, i.e. nuclear burn time scale and convective mixing time scale are similar. The ultimate goal is to develop a better understanding of convective mixing in stellar evolution, and the formation of the elements in the first generations of stars, where this nucleosynthesis and hydrodynamics regime is believed to be important.
