Introduction
• Supernova (SN):
Core collapse/ “Type II, Type Ib, ...etc.” SN (massive star, with H-line)
Thermonuclear disruption of accreting Carbon-Oxygen white dwarfs/ “Type Ia” (without H-line)
• Light curves of Type Ia SN:
Peak luminosity and decay time scale correlated (standard candle)
All roughly similar, but real variations seen

Why are SNe Ia important?
• The use of SNe Ia as one of the main ways to determine key cosmological parameters.
• Galaxy evolution depends on the radiative kinetic energy and nucleosynthetic output of SNe Ia.
• Estimating more accurate SN Ia rates and understanding the physics of SN remnants will help to place meaningful constraints on the theory of binary evolution.

Key Questions
• Can companion’s hydrogen be hidden?
• What happens to the companion after the supernova explosion?
• What is the intrinsic variation of Type Ia supernova?
• Can we detect the remnant companion star in the supernova remnant?

Code Optimization
17
• High performance computing is required in this project.
• We developed an automatic MPI to AMPI program transformation tool using Photran (Negara et al. 2010)
• Working on a AMR framework using Charm++ (Langer et al. 2011, in prep. )

Conclusions• Investigated the impact of SN
Ia ejecta on a companion star.
• A power-law relation between the unbound mass and initial separation is found
• Kick velocity can also fitted by a power law
• ~10-4 solar mass nickel contamination which is larger than the solar abundance
• High performance computing is required in this project.
• A tool to automatic MPI to AMPI transformation
• Charm++ AMR framework

• Combine the radiation process with fluids
• Predict supernova light curves
• Compare with observations
• Improve the performance and load balancing
• Study possible replacement of PARAMESH with Charm++ library
