Consequence of total lepton number violation in strongly magnetized iron   white dwarfs
  The influence of neutrinoless electron to positron conversion on cooling of strongly magnetized iron white dwarfs is studied. It is shown that they can be good candidates for soft gamma-ray repeaters and anomalous X-ray pulsars.
