The SuperNova Explosion Code is a new spherically-symmetric Lagrangian radiation-hydrodynamics code designed to follow supernova explosions through the envelope of their progenitor star, produce bolometric (and approximate multi-color) light curve predictions, and provide input to spectral synthesis codes for spectral modeling. SNEC is part of the Simulating eXtreme Spacetime (SXS) Collaboration's effort to predict the multi-messenger signatures of extreme astrophysical phenomena. SNEC's development is partially supported by NSF award nos. AST-1205732 and AST-1212170, by the Sherman Fairchild Foundation, and by Caltech.
The primary SNEC authors are Viktoriya Morozova, Christian Ott, and Anthony L. Piro. The new SNEC version 1.01 contains contributions from Brian W. Mulligan (University of Texas, Austin).
SNEC's current features include:
- 1D (spherical) Lagrangian Newtonian hydrodynamics with artificial viscosity following the formulation of Mezzacappa & Bruenn (1993).
- Stellar equation of state with a Saha solver ionization/recombination based on Paczynski 1983 and Frank Timmes's equation of state and Saha solver.
- Equilibrium flux-limited photon diffusion with OPAL opacities and low-temperature opacities from http://webs.wichita.edu/physics/opacity/.
- Prediction bolometric light curves and multi-color lightcurves (in the blackbody approximation).

The blcode -- the pure hydro version of SNEC
The blcode is a slightly modified implementation of the Mezzacappa & Bruenn (1993) hydrodynamics scheme. It is nearly identical to the hydrodynamics solver in SNEC. The implementation details are discussed in blcode_notes.pdf and a tarball with the source code can be downloaded here: blcode.tar.gz. Note that this tarball does not contain the source code and data table of Frank Timmes's Helmholtz EOS, which must be obtained separately from Frank's webpage.
