超新星（SN）和超新星遗迹（SNRs）在星际尘埃的生命周期中起着重要作用。超新星爆炸产生的快速冲击波横扫星际空间，摧毁尘埃颗粒，改变它们的物理和化学性质。另一方面，致密、冷却的SN喷出物为尘埃凝结提供了环境。最近的太空红外望远镜揭示了与这些迷人的微观过程有关的隐藏宇宙。本文介绍了AKARI对年轻核坍缩超新星遗迹中星尘的研究结果。AKARI的结果显示了与SNRs相关的星尘的不同红外特征，这意味着爆炸时不同的物理/化学恒星结构和星周环境。
Supernovae (SN) and supernova remnants (SNRs) play a major role in the life-cycle of interstellar dusts. Fast shock waves generated by SN explosions sweep out the interstellar space destroying dust grains and modifying their physical and chemical properties. The dense, cooling SN ejecta, on the other hand, provide an environment for dusts to condense. Recent space-infrared telescopes have revealed the hidden universe related to these fascinating microscopic processes. In this paper, I introduce the results on stardusts in young core-collapse supernova remnants obtained by AKARI. The AKARI results show diverse infrared characteristics of stardusts associated with SNRs, implying diverse physical/chemical stellar structures and circumstellar environments at the time of explosion.
