Plasmon decay to a neutrino pair via neutrino electromagnetic moments in   a strongly magnetized medium
  We calculate the neutrino luminosity of a degenerate electron gas in a strong magnetic field via plasmon decay to a neutrino pair due to neutrino electromagnetic moments and obtain the relative upper bounds on the effective neutrino magnetic moment.
