The Origin of Giant Pulse and Its Correlation with X-ray and PeV Emission of the Crab Pulsar

摘要:
In creasing observation of microstructures, in particular  giantpulses   
  require a pulsar emission mechanism with
small size, high energy density,
pair production along with  Alfven wave, which give rise   
coherent trains responsible for subsequent pulsar emission.
However,  it is still difficult to reproduce these fundamental elements  in polar-cap based models.
This paper proposes a reconnection process at the tip of last closed field line  region with a current sheet of width, $\sim 10^{-1}$m and length, $10^1$m,  in the vicinity of light cylinder.
The resultant interaction of triple beams out of the X-line of  reconnection site  lead to
micostructures distributing in a
cone-core pattern of pulsar emission.
The new scenario can interpret not only  the frequency and power of giantpulses, but also their
correlation with  X-ray and PeV emission exhibited in the Crab pulsar.
