从年轻到年老:脉冲星风星云的演化路径

From young to old: the evolutionary path of Pulsar Wind Nebulae

Barbara Olmi, Niccolò Bucciantini

摘要:

脉冲星风星云是迷人的系统,也是高能天体物理学的典型来源。由于它们的邻近,亮度,它们在多波长下发光的事实,特别是它们在伽马射线下的长寿命发射,模拟它们的属性对于正确解释可见星系特别重要。这方面的一个复杂因素是它们在不同年龄表现出的各种性质和形态。在这里,我们讨论了脉冲星风星云的演化阶段之间的差异,它们在过去是如何被模拟的,以及最近取得了哪些进展。我们从现象学,理论(特别是数值)和观测的角度来讨论,特别注意最近的结果和开放的问题,这些有趣的来源的物理。

英文摘要:

Pulsar wind nebulae are fascinating systems, and archetypal sources for high-energy astrophysics in general. Due to their vicinity, brightness, to the fact that they shine at multi-wavelengths, and especially to their long-living emission at gamma-rays, modelling their properties is particularly important for the correct interpretation of the visible Galaxy. A complication in this respect is the variety of properties and morphologies they show at different ages. Here we discuss the differences among the evolutionary phases of pulsar wind nebulae, how they have been modeled in the past and what progresses have been recently made. We approach the discussion from a phenomenological, theoretical (especially numerical) and observational point of view, with particular attention to the most recent results and open questions about the physics of such intriguing sources.
