The team’s XRB simulations will provide insight into the rapid proton capture process nucleosynthesis, connect with observations, and probe the structure of the underlying neutron star. These are all multiscale, multiphysics problems whose calculation requires the coupling of hydrodynamics, magnetic fields, reactions, gravity and diffusion. The first project, “Approaching Exascale Models of Astrophysical Explosions,” includes Principal Investigator Professor Michael Zingale and co-investigators Associate Professor Alan Calder, Postdoctoral Associate Alice Harpole and PhD student Maria Barrios Sazo.īuilding on more than a decade of work, this project aims to produce models of burning and flame propagation on neutron stars as models for X-ray bursts (XRBs), investigate white dwarf mergers and the role of magnetic fields, and explore the end state of massive star convection.
Through these awards, the research teams will be able to access the leadership-class supercomputers at DOE’s Argonne and Oak Ridge National Laboratories. Department of Energy’s (DOE) Office of Science for 2022 through its Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program. Two high-impact computational science projects that include Stony Brook University faculty from the Department of Physics and Astronomy have been awarded supercomputer access from the U.S.
