Comment on "Ponderomotive force due to neutrinos"
  The derivation of the ponderomotive force due to neutrinos by Hardy and Melrose, Phys.Rev.D v.54, p.6491 (1996) is based on a flawed analysis of the ponderomotive force concept. Their conclusions also contain an erroneous physical assumption related to the neutrino emission in supernovae. A correct analysis shows the importance of the ponderomotive force due to neutrinos in type II supernovae explosions.
