Abstract

The results of the calculations of the neutrino energy-loss rates resulting from pair, photo-, plasma, bremsstrahlung, and recombination neutrino processes are summarized in the form of analytic fitting formulae and tables. Care has been taken in order to serve the convenience of the users of these results. We have tried to make the present paper as as possible. The contents of the present paper are intended to serve as useful physical input data for stellar evolution computations. We intend to publish the numerical data and the FORTRAN codes for the results of the neutrino energy-loss rates in the CD-ROM series of the American Astronomical Society. in the CD-ROM, we intend to give three options for the FORTRAN codes. The first option comprises the results with analytic fitting formulae only. The second option comprises the results with analytic fitting formulae for the bremsstrahlung and recombination neutrino processes, and the numerical tables for the pair, photo-, and plasma neutrino processes with a standard quadratic interpolation procedure. In this option, the grid of log T for the pair neutrino energy-loss rate is 0.2. The third option is a variant of the second option, with the replacement of the grid of log T for the pair neutrino energy-loss rate to be 0.05.
