对Ia型超新星遗迹SN 1006的多波段观测表明，它在射电、光学和X射线波段的发射形态具有特殊的性质。在硬X线片中，残留物是双侧的，有两个相对的明亮的肢体，有突出的突起。此外，在无线电，光学和软X射线波长处已经检测到灯丝。使用3D HD模拟研究了残骸形态中这些特殊特征的原因。假设超新星喷出物是在密度不连续的环境介质中演化的，在稀薄介质中，残骸的边界半径较小，壳层由两个半径不同的半球组成。沿着沿着特定的视线，由于来自具有较大半径的半球的边缘的发射位于来自小半球的壳的发射之外，因此在残余物的外围上出现突起。此外，SN 1006的西北灯丝是由于视线与两个半球边缘附近的受冲击物质相交而产生的。可以得出结论，SN1006的形态中的东北和西南翼上的突起和西北灯丝可以被再现为与具有密度不连续性的介质相互作用的残余物。
Multiband observations on the Type Ia supernova remnant SN 1006 indicate peculiar properties in its morphologies of emission in the radio, optical, and X-ray bands. In the hard X-rays, the remnant is bilateral with two opposite bright limbs with prominent protrusions. Moreover, a filament has been detected at the radio, optical, and soft X-ray wavelengths. The reason for these peculiar features in the morphologies of the remnant is investigated using 3D HD simulations. With the assumption that the supernova ejecta are evolved in the ambient medium with a density discontinuity, the radius of the remnant’s boundary is smaller in the tenuous medium, and the shell consists of two hemispheres with different radii. Along particular line of sights, protrusions appear on the periphery of the remnants since the emission from the edge of the hemisphere with a larger radius is located outside that from the shell of the small hemisphere. Furthermore, the north-west filament of SN 1006 arises as a result of the intersection of the line of sight and the shocked material near the edges of the two hemispheres. It can be concluded that the protrusions on the north-east and south-west limbs and the north-west filament in the morphologies of SN 1006 can be reproduced as the remnants interacting with the medium with a density discontinuity.
