超新星遗迹(SNR)的尘埃质量通常用作估算超新星爆发的喷流物产生的尘埃质量，对河外超新星遗迹SN1987A[1] [2]和河内超新星遗迹Cassiopeia A(Cas A)[3]的研究表明超新星爆发产生的尘埃范围从千分之几的太阳质量到2-4M⊙。与超新星是尘埃的重要来源相反，超新星会通过其爆发时产生剧烈的激波通过溅射和粉碎过程破坏其周遭环境中的尘埃。

The dust mass of supernova remnant(SNR) is often used to estimate the dust mass pruced by the ejecta of the supernovae(SNe). Studies of the extragalactic supernova remnant and the supernova remnant in the Milky Way show that the dust pruced by the supernova explosion ranges from a few thousandths of the solar mass to 2-4M⊙. In contrast to supernovae, which is an important dust prucer, supernovae destroy dust in their surrounding environment through the process of sputtering and shattering by violent shock. The dust temperature and mass of the supernova remnants (SNRs) in M31 are estimated by fitting the infrared spectral energy distribution calculated from the images in the Spitzer/IRAC8 and MIPS24, Herschel/PACS70, 100, 160, and Herschel/SPIRE250, 350 µm band. Twenty SNRs with relatively reliable photometry exhibit an average dust temperature of 20.1 +1.8 −1.5 K, which is higher than the surrounding and indicating the heating effect of supernova explosion. The dust mass of these SNRs ranges from about 100 to 800 M⊙, much bigger than the SNRs in the Milky Way. On the other hand, this yields the dust surface density of 0.10+0.07 −0.04 M⊙pc−2 , about half of the surrounding area, which implies that about half dust in the SNRs is destroyed by the supernova explosion. The dust temperature, the radius, and thus the dust mass all demonstrate that the studied SNRs are old and very likely in the snowplow or even fade away phase because of the limitation by the far distance and observation resolution of M31, and the results can serve as a reference to the final effect of supernova explosion on the surrounding dust. The dust temperature and mass of the supernova remnants in Small Magellanic Cloud(SMC) are estimated by fitting the infrared spectral energy distribution calculated from the images in the Spitzer/IRAC8 and MIPS24, Herschel/PACS70, 100, 160, and Herschel/SPIRE250, 350,500 µm band. Six SNRs with relatively reliable photometry exhibit an average dust temperature of 22.7 K. The dust mass of these SNRs ranges from about 25 to 120 M⊙, simliar to the SNRs in the Milky Way. On the other hand, this yields the dust surface density of 0.06 M⊙pc−2 .Since the size of the supernova remnants in SMC is larger than the size of the supernova remnants in the Milky Way, although the metallicity of SMC is only 1/10 of that of the Milky Way, the dust mass of the supernova remnants is comparable to that of the supernova remnants in the Milky Way.
