Abstract
A proper account of mean field effects for nucleons leads to a slight increase in the value of the nucleons chemical potential with respect to the values used in our original work. Though the ratio of the complete axion emissivity over the OPE calculation is not strongly affected by the changes we report here, the absolute value of the complete emissivity increases significantly with respect to our previous calculation. As a consequence, the bound on the axion mass is strengthened with respect to what we had previously reported.
