subroutine Burn_nseAtDens ( real  qbar_nse,
real  sumyi_nse,
real  approxtemp,
real  edot,
real  Yedot,
real  Ye,
real  dens,
real  emq 

This function gives the NSE final state for a constant density burn via table lookup. qbar is returned in MeV/nucleon. Only the compositional information (qbar, 1/Abar, edot, Yedot) should be used for hydrodynamics purposes. Accurate thermodynamic prperties of the NSE final state (rho, T) should be obtained by solving eint - qbar_nse = emq . This is important due to the limited accuracy of the table interpolation (i.e., the interpolated values cannot satisfy any constraints on their own.)

qbar_nse – Average binding energy per nucleon (averaged over nse) sumyi_nse – Sum over the abundances. (Y = X/A = X/(#of nucleons)) approxtemp – ?? Ask Dean edot – Neutrino and anti-neutrino loss rates [ergs/g] Yedot – Change in electron fraction wrt time (neutronization rate) Ye – Electron fraction dens – Density in/out emq – E-Q = Internal energy minus binding energy (per volume?)

NOTES Takes place after burning is complete. NSE expands after burning and the equilibrium state is a function of the density and the temperature. Been burned, flame is done, but then the hot stuff expands. This changes the composition and releases energy.
