Scientific paper

The authors propose, as a model for gamma-ray bursts, that the energy released by the thermonuclear runaway at the surface of a magnetized neutron star is converted into gamma-ray photons by small scale magnetic field reconnection. Most of the energy flux is transported up to the atmosphere by Alfvén waves, driven by oscillatory magnetoconvection. The electric field created by reconnection accelerates electrons to very high energies. The excitation of Landau levels by collisions is followed by gamma-ray synchrotron emission. The time scales, energies, and luminosities involved agree with the observations.
