    Abstract

    We calculate the time dependent line and recombination spectrum of non-equilibrium plasma heated by strong radiation as a test model of X-ray line emission of GRB afterglows. Our calculation shows that the non-equilibrium effect of the plasma is complex and important in the time evolution of the spectrum. The origin of these lines is puzzling us, but it is essential to understand the nature of GRBs and their circumstellar matter.
