摘要:

我们介绍了一个偶然发现的红外明亮的超新星遗迹(SNR)B 0104 -72.3的小麦哲伦云的红外相机(IRC)机载AKARI。在所有四个观察到的IRC带中检测到一个细长的,部分完整的外壳,覆盖2.6-15 μ m。红外壳层围绕着与SNR相关的无线电,光学和X射线发射,可能是辐射SNR壳层。这是第一次在小麦哲伦星云中探测到近/中红外波段的SNR壳层。IRC颜色表明红外发射可能来自受冲击的H2分子,其中一些可能来自离子线。我们的结论是,B 0104 -72.3是一个中年SNR与分子云相互作用,类似于银河SNR IC 443。我们的研究结果突出了AKARI IRC观测在研究SNR,特别是诊断SNR冲击方面的潜力。

英文摘要:

We present a serendipitous detection of the infrared-bright supernova remnant (SNR) B0104-72.3 in the Small Magellanic Cloud by the Infrared Camera (IRC) onboard AKARI. An elongated, partially complete shell is detected in all four observed IRC bands covering 2.6-15 um. The infrared shell surrounds radio, optical, and X-ray emission associated with the SNR and is probably a radiative SNR shell. This is the first detection of a SNR shell in this near/mid-infrared waveband in the Small Magellanic Cloud. The IRC color indicates that the infrared emission might be from shocked H2 molecules with some possible contributions from ionic lines. We conclude that B0104-72.3 is a middle-aged SNR interacting with molecular clouds, similar to the Galactic SNR IC 443. Our results highlight the potential of AKARI IRC observations in studying SNRs, especially for diagnosing SNR shocks.
