Abstract Using the shell-model Monte Carlo method and random phase approximation theory, we carry out an estimation on neutrino energy loss (NEL) of 52,53,54,55,56Fe. We find the NEL rates increase greatly at some typical stellar conditions, and even exceed eight orders of magnitude. On the other hand, in order to compare our results of λSMMCLJ (which are calculated by using the SMMC method) with those of λFFNLJ (which are calculated by using the Fuller-Fowler-Newman (FFN) method), the error factor C, between λSMMCLJ and λFFNLJ, is discussed and shows that at higher density and temperature, the fit is fairly good for the two results (λSMMCLJ and λFFNLJ), and the maximum error is ～6.20%. However, the maximum error is ～95.50% (e.g. 53Fe) at lower density and temperature.
