High-energy emission from pulsar outer magnetospheres.

HIROTANI K.

Abstract (from CDS):

We investigate particle accelerators in rotating neutron-star magnetospheres by simultaneously solving the Poisson equation for the electrostatic potential together with the Boltzmann equations for electrons, positrons, and photons on the poloidal plane. Applying the scheme to the three pulsars, Crab, Vela, and PSR B1951+32, we demonstrate that the observed phase-averaged spectra are basically reproduced from infrared to very high energies. It is found that the Vela's spectrum in 10-50 GeV is sensitive to the three-dimensional magnetic field configuration near the light cylinder; thus, a careful argument is required to discriminate the inner-gap and outer-gap emissions using a gamma-ray telescope like GLAST. It is also found that PSR B1951+32 has a large inverse-Compton flux in TeV energies, which can be detected by ground-based air Cerenkov telescopes as a pulsed emission.
