费米脉冲星的距离和转动惯量

Distances and moments of inertia of Fermi Pulsars

Andrei Gruzinov

摘要:

距离和转动惯量的测量必须是有用的,例如,三维映射的色散和旋转措施,约束核物质状态方程等的距离和转动惯量可以通过拟合的伽马射线光变曲线测量的伽马射线辐射,因为伽马射线发射似乎是由容易计算的物理。(第一原理)理论光变曲线只计算了弱双曲星(光柱附近的电子对产生量远小于Goldreich-Julian [1]的每转),而且精度不够;但是,由于这个计算是由自学成才的数值家完成的,所以一定有可能提高弱双曲星的理论精度,也可以将计算扩展到非弱双曲星。为了邀请装备更好的研究人员的计算工作,我们描述了一个(完全显而易见的)程序来测量弱双星的距离和惯性矩。

英文摘要:

Measurement of distances and moments of inertia of pulsars must be useful, for instance, for three-dimensional mapping of the dispersion and rotation measures, constraining the nuclear equation of state, etc. The distances and moments of inertia can be measured by fitting the gamma-ray lightcurves of pulsars, because the gamma-ray emission seems to be governed by easily calculable physics. The (first-principle) theoretical lightcurves have been computed only for weak pulsars (pair production near the light cylinder much smaller than Goldreich-Julian [1] per rotation), and at insufficient accuracy; but, since this computation has been done by a self-taught numericist, it must be possible to improve the theoretical accuracy for weak pulsars, and also to extend the computation to non-weak pulsars. To invite the computational effort of better-equipped researchers, we describe an (entirely obvious) procedure for measuring the distances and moments of inertia for weak pulsars.
