超新星遗迹的红外辐射:尘埃的形成和破坏

Infrared Emission from Supernova Remnants: Formation and Destruction of Dust

Brian J. Williams, Tea Temim

摘要:

本文综述了超新星遗迹(SNRs)和超新星(SNe)的尘埃辐射观测.理论计算表明,超新星,特别是核心坍缩,应该会产生大量的尘埃,可能相当于太阳质量。对河外SNe的观测还没有发现接近这个数量的任何地方,但这可能是观测限制的结果。SN 1987 A在从SN转变为SNR的过程中,确实显示出在其喷出物中形成大量尘埃的迹象,但这些尘埃是否会在注入ISM的反向冲击中幸存下来尚不清楚。红外线对超新星的观测并没有发现大量的尘埃,而且观测到的尘埃通常是被前向激波扫起的,而不是在喷出物中产生的。因为冲击波也会摧毁ISM中的尘埃,所以我们探讨SNe是否可能是宇宙中尘埃的净破坏者,而不是净创造者的问题。

英文摘要:

We review the observations of dust emission in supernova rem- nants (SNRs) and supernovae (SNe). Theoretical calculations suggest that SNe, particularly core-collapse, should make significant quantities of dust, perhaps as much as a solar mass. Observations of extragalactic SNe have yet to find anywhere near this amount, but this may be the result of observa- tional limitations. SN 1987A, in the process of transitioning from a SN to an SNR, does show signs of a significant amount of dust forming in its ejecta, but whether this dust will survive the passage of the reverse shock to be injected into the ISM is unknown. IR observations of SNRs have not turned up significant quantities of dust, and the dust that is observed is generally swept-up by the forward shock, rather than created in the ejecta. Because the shock waves also destroy dust in the ISM, we explore the question of whether SNe might be net destroyers, rather than net creators of dust in the universe.
