标题： The Effect of the Gravitational Mass on the Electromagnetic Radiation from an Oblique, Relativistically Rotating Dipole (Neutron Star)

摘要： 基于脉冲星的磁偶极子模型，我们利用 Haxton-Ruffini [31] 对单电荷扩展工作的基础上，结合 DePaolis-Ingrosso-Qadir [32] 关于倾斜旋转磁偶极子的研究，将引力质量的影响纳入其中。通过使用辐射微分方程的数值和解析解，我们构建了不同质量双星-中子星系统的能量谱。这些谱表明，在相对较低的角动量 \(l\) 下，引力质量对抑制相对论增强因子的影响非常显著，与之前的研究 [27, 28, 32] 相比，这种抑制效应随着质量从 0.5 倍太阳质量变化到 3 倍太阳质量时，增加了两到三个数量级。这表明中子星的大部分角动量以旋转动能的形式保留下来，而不是以电磁能形式辐射出去。此外，辐射能量的抑制在一定程度上与角动量和高自转速度无关。我们还发现电磁能与倾角（偏心角）的正弦平方成正比，这与经典行为类似。然而，在非常高的角动量情况下，整个辐射被抑制，质量的影响可以忽略不计。这表明，引入质量效应后，预期的（狭义）相对论增强效应被（广义）相对论角动量增加所取代。 显示英文摘要

摘要： Relying on the magnetic dipole model of the pulsar, we use the extension of the work of Haxton-Ruffini [31] for single charges by DePaolis-Ingrosso-Qadir [32] for an obliquely rotating magnetic dipole, to incorporate the effect of the gravitational mass. So, by using the numerical and analytical solutions of the differential equation for the radiation, we construct the energy spectra for different masses of the dipole-NS. These spectra show that, in relatively low angular momentum l, the effect of the gravitational mass is very significant in suppressing the relativistic enhancement factor, which had been found [27, 28, 32], by two to three orders of magnitude, as the mass changes from 0.5 solar mass to 3 solar masses. It is an indication that most of the angular momentum of the NS is retained as rotational kinetic energy instead of being radiated as an electromagnetic energy. Also, the suppressing in radiation energy is more or less independent of the angular momentum, and the high rotational velocity. We also found that electromagnetic energy is proportional to square of sin(inclination angle the obliquity) which is similar to the classical behavior. However, in the very high angular momentum, the whole radiation suppresses and the effect of mass is neglected. It indicates that the (special) relativistic enhancement expected is lost to the (general) relativistic increase of angular momentum after incorporating the effect of mass.
