我们利用斯皮策和赫歇尔的观测结果,在候选超新星遗迹(SNR)“龙卷风”(G357.7-0.1)的多个区域内呈现了复杂的尘埃结构。我们使用点过程映射,ppmap,调查在8弧秒的分辨率的旋风尘埃的分布,相比,本地望远镜光束的5-36弧秒。我们在龙卷风的头部和尾部都发现了复杂的尘埃结构,温度范围从15到60 K。头部的冷尘埃形成了一个壳,与无线电发射有一些重叠,在X射线峰值处包裹着温暖的尘埃。类似于陆地上被称为“尘魔”的桑迪旋风,我们发现龙卷风中含有大量的灰尘。假设尘埃吸收系数为κ300= 0.56,我们得出龙卷风头的总尘埃质量为16.7,这可以解释为在致密区域扩展的SNR扫起的星际物质。龙卷风头部的X射线、红外线和无线电发射表明这是一个SNR。尾巴的起源更不清楚,虽然我们提出有一个X射线双星嵌入在SNR中,流出的驱动器进入SNR壳。这种相互作用以类似于SNR W50和微类星体SS 433的方式形成了螺旋尾结构。
We present complicated dust structures within multiple regions of the candidate supernova remnant (SNR) the ‘Tornado’ (G357.7–0.1) using observations withSpitzerandHerschel. We use point process mapping,ppmap, to investigate the distribution of dust in the Tornado at a resolution of 8 arcsec, compared to the native telescope beams of 5–36 arcsec. We find complex dust structures at multiple temperatures within both the head and the tail of the Tornado, ranging from 15 to 60 K. Cool dust in the head forms a shell, with some overlap with the radio emission, which envelopes warm dust at the X-ray peak. Akin to the terrestrial sandy whirlwinds known as ‘dust devils’, we find a large mass of dust contained within the Tornado. We derive a total dust mass for the Tornado head of 16.7, assuming a dust absorption coefficient of κ300= 0.56, which can be explained by interstellar material swept up by a SNR expanding in a dense region. The X-ray, infrared, and radio emission from the Tornado head indicate that this is a SNR. The origin of the tail is more unclear, although we propose that there is an X-ray binary embedded in the SNR, the outflow from which drives into the SNR shell. This interaction forms the helical tail structure in a similar manner to that of the SNR W50 and microquasar SS 433.
