Numerical modeling of stellar mergers associated with massive and high mass-ratio binary systems from the onset of the merger and the associated "merge-burst" transient to the long-term evolution of the post-merger remnant star in order to (a) understand the transients associated with stellar mergers, (b) make connections to observations of stars with unusual properties and (c) constrain the circumstellar environments produced by merge-bursts around massive stars and the implications for their eventual supernovae. The researcher will assist the numerical modeling efforts using world-class computing resources in close collaboration with the PI, and will be directly involved with the use, testing and expansion of numerical hydrodynamics software instruments often used in computational astrophysics in order to simulate the properties of massive and high mass-ratio stellar mergers.
Minimum qualifications: Ph.D. in physics or related field; Experience in numerical methods in astrophysics, stellar evolution and/or stellar nucleosynthesis.
(Senior Level) Additional three years of postgraduate experience in Numerical Methods in Astrophysics, Theoretical Astrophysics, Stellar Evolution, Numerical Hydrodynamics with AMR or SPH codes, or Stellar nucleosynthesis.
Good understanding of radiation transport physics and astrophysical radiative processes and associated modeling methods.
- Experience in modeling of stellar merger or related phenomena with numerical hydrodynamics codes;
- Experience with numerical stellar evolution and use of 3D hydrodynamics codes commonly used to simulate a multitude of astrophysical phenomena, including stellar mergers;
- Understanding of radiation transport physics, astrophysical radiative processes, associated modeling methods and parallel computing on supercomputering clusters;
- Strong background in computational astrophysics.
