Abstract:Relations between radio surface brightness (sigma) and diameter (D) of supernova remnants (SNRs) are important in astronomy. In this paper, following the work Duric and Seaquist (ApJ 301:308, 1986) at adiabatic phase, we carefully investigate shell-type supernova remnants at radiative phase, and obtain theoretical sigma-D relation at radiative phase of shell-type supernova remnants at 1GHz. By using these theoretical sigma-D relations at adiabatic phase and radiative phase, we also roughly determine phases of some supernova remnant from observation data.
