摘要

脉冲星风星云(PWN)是令人着迷的系统，也是高能天体物理学的典型来源。由于它们的邻近，亮度，以及它们在多波长下发光的事实，特别是它们在伽马射线上的长寿命发射，对它们的特性建模对于正确解释可见星系尤为重要。这方面的一个复杂之处在于，它们在不同的年龄表现出不同的性质和形态。在这里，我们讨论了PWN进化阶段之间的差异，它们在过去是如何建模的，以及最近取得了哪些进展。我们从现象学、理论(特别是数值)和观测的角度进行讨论，特别关注这些有趣来源的物理学的最新结果和开放问题。

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

Abstract Pulsar wind nebulae (PWN) 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 PWN, 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.
