超新星遗迹中中子星的初始自旋周期

Initial spin periods of neutron stars in supernova remnants

S. B. Popov, R. Turolla

摘要:

我们提出的估计初始自旋周期,$P_0$,与超新星遗迹的射电望远镜。通过使用30个物体的已发表数据,我们能够得出一个可靠的估计,在许多情况下,假设标准的磁偶极子自旋下降(制动指数n=3)的初始自旋周期。我们的一组估计仍然不足以推断出初始周期分布的确切形状。然而,我们表明,高斯分布的平均值和偏差$\sim 0.1$ s是与我们的结果是一致的,而平坦的,广泛的分布和非常窄的不利。

英文摘要:

We present estimates of initial spin periods, $P_0$, for radio pulsars associated with supernova remnants. By using the published data on 30 objects, we were able to derive a reliable estimate for the initial spin period, assuming standard magneto-dipole spin-down (braking index n=3), in many cases. Our set of estimates is still not sufficient to infer the exact shape of the initial period distribution. However, we show that a gaussian distribution with mean and deviation $\sim 0.1$ s is consistent with our results, while flat, wide distributions and very narrow ones are disfavored.
