论文摘要

脉冲星的伽马射线照明量被认为超过了其无线电亮度,但基于以下假设,即伽马射线脉冲脉冲距离衰减的假设像无线电脉冲的通量一样,遵守反平方向。但是,测试通过efron-petrosian统计数据测试仪表脉冲的独立性和距离脉冲脉冲的距离的结果,这意味着第二个{\ it fermi}目录中的观察数据与依赖性$ s \ s \ 3/2/3/3/2/3/3/3/3/3/3/3/3/fl fl fl fl fl fl fl fl fl flly pul s of s $ s y y fl fl fl fl fllas y s $ s in与依赖关系$ s \ propto d^{-2} $相比,其意义水平。这与能源保护的要求不兼容,因为Ardavan中描述的辐射过程[{\ it Mon。不是。 R.

Pulsars' gamma-ray luminosities are thought to exceed their radio luminosities by several orders of magnitude: a notion that is based on the assumption that the decay with distance of the flux of gamma-ray pulses obeys the inverse-square law as does that of the flux of radio pulses. However, results of testing the hypothesis of independence of luminosities and distances of gamma-ray pulsars by means of the Efron--Petrosian statistic imply that the observational data in the second {\it FERMI} catalogue are consistent with the dependence $S\propto D^{-3/2}$ of the flux densities $S$ of these pulsars on their distances $D$ at substantially higher levels of significance than they are with the dependence $S\propto D^{-2}$. This is not incompatible with the requirements of the conservation of energy because the radiation process described in Ardavan [{\it Mon. Not. R. Astron. Soc.}, {\bf 507}, 4530--4563 (2021)], by which the superluminally moving current sheet in the magnetosphere of a neutron star is shown to generate the observed gamma-ray pulses, is intrinsically transient: the difference in the fluxes of power across any two spheres centred on the star is balanced by the change with time of the energy contained inside the shell bounded by those spheres. Once the over-estimation of their values is rectified, the luminosities of gamma-ray pulsars turn out to have the same range of values as do the luminosities of radio pulsars.
