Abstract


Geometrical properties of the annular gap model, efforts of observational tests on it and applications of the model to explain the bi-drifting phenomenon are introduced in this paper. It was shown that in the frame of the annular gap model the observed γ-ray and radio radiation properties of pulsars can be well reproduced. The annular gap model can naturally explain the bi-drifting phenomenon, which is difficult to be understood in classical inner vacuum models. Recently, Wang et al. proposed an independent geometrical method to determine the location for the multi-band radiation regions of PSR B1055–52. They found that the γ-ray emission and radio main pulse emission come from the annular gap, while the radio inter-pulse originates from the core cap region. The results show that the constrained radio and γ-ray emission regions are generally consistent with the predictions of the annular gap model.
