解释Gamma-Ray脉冲星光变曲线的图谱
An Atlas For Interpreting Gamma-Ray Pulsar Light Curves
摘要:
我们已经模拟了人口的年轻的自旋供电的恒星和计算的光束模式和光变曲线的三个主要的几何模型:极帽发射,两极焦散(“槽隙”)发射和外磁层发射。光变曲线的形状敏感地依赖于磁倾角α和视角ζ。我们提出的结果,如峰的多重性和伽玛射线峰分离(α,ζ)平面的可观的地图。这些图可以用来定位无线电响亮和无线电安静的辐射源的允许区域,并将观测到的通量转换为真正的全天辐射。
英文摘要:
We have simulated a population of young spin-powered pulsars and computed the beaming pattern and lightcurves for the three main geometrical models: polar cap emission, two-pole caustic ("slot gap") emission and outer magnetosphere emission. The light curve shapes depend sensitively on the magnetic inclination alpha and viewing angle zeta. We present the results as maps of observables such as peak multiplicity and gamma-ray peak separation in the (alpha, zeta) plane. These diagrams can be used to locate allowed regions for radio-loud and radio-quiet pulsars and to convert observed fluxes to true all-sky emission.
