SOME PROPERTIES OF DETONATION WAVES IN DENSE STELLAR MATERIAL
- Date Issued:
- 1973
- Summary:
- The time history of the abundances of 13 nuclei and the thermodynamic and hydrodynamic variables in the burning zone of a detonation wave were numerically followed in detail by coupling a nuclear reaction network to the Rankine-Hugoniot relations and accurate equations of state. A number of computations were performed for material with initial densities and temperatures in the range 10^9 < p < 10^11(g/cm^3) and 3 x 10^8 K, respectively, and compositions consisting of C^12 and O^16, and O^16, Mg^24, and Si^28. From such computations it is concluded that: (1) the nuclear rea-tion rate doubling timescale approximation gives an accurate nuclear burning timescale, (2) the propagation of a detonation wave fueled by O^16 at very high densities is virtually assured, (3) the correct energy release is obtained assuming nuclear statistical equilibrium behind the detonation wave, and this latter assumption is good, (4) the Chapman- Jouguet hypothesis is adequate in spite of the fact that the actual form of the detonation wave is more likely that of a weak detonation.
