Query: A moderately-sized nuclear network to assist multi-D hydrodynamic
  simulations of supernova explosions   A key ingredient in any numerical study of supernova explosions is the
nuclear network routine that is coupled with the hydrodynamic simulation code.
When these studies are performed in more than one dimension, the size of the
network is severely limited by computational issues. In this work, we propose a
nuclear network, net87, which is close to one hundred nuclei and could be
appropriate to simulate supernova explosions in multidimensional studies. One
relevant feature is that electron and positron captures on free protons and
neutrons have been incorporated to the network. Such addition allows for a
better track of both, the neutronized species and the gas pressure. A second
important feature is that the reactions are implicitly coupled with the
temperature, which enhances the stability in the nuclear statistical
equilibrium (NSE) regime. Here we analyze the performance of net87 in light of
both: the computational overhead of the algorithm and the outcome in terms of
the released nuclear energy and produced yields in typical Type Ia Supernova
conditions.
