Modeling Multi-wavelength Pulse Profiles of Millisecond Pulsar PSR B1821-24
PSR B1821\(-\)24 is a solitary millisecond pulsar (MSP) which radiates multi-wavelength pulsed photons. It has complex radio, X-ray and \(\gamma\)-ray pulse profiles with distinct peak phase-separations that challenge the traditional caustic emission models. Using the single-pole annular gap model w...

| description | PSR B1821\(-\)24 is a solitary millisecond pulsar (MSP) which radiates multi-wavelength pulsed photons. It has complex radio, X-ray and \(\gamma\)-ray pulse profiles with distinct peak phase-separations that challenge the traditional caustic emission models. Using the single-pole annular gap model with suitable magnetic inclination angle (\(\alpha=40^\circ\)) and viewing angle (\(\zeta=75^\circ\)), we managed to reproduce its pulse profiles of three wavebands. It is found that the middle radio peak is originated from the core gap region at high altitudes, and the other two radio peaks are originated from the annular gap region at relatively low altitudes. Two peaks of both X-ray and \(\gamma\)-ray wavebands are fundamentally originated from annular gap region, while the \(\gamma\)-ray emission generated from the core gap region contributes somewhat to the first \(\gamma\)-ray peak. Precisely reproducing the multi-wavelength pulse profiles of PSR B1821\(-\)24 enables us to understand emission regions of distinct wavebands and justify pulsar emission models. |
