论文摘要
年轻的壳型超新星残留RCW 103具有Chandra获得的X射线形态中具有特殊的特性。 X射线中的东南壳更明亮，并且该区域的壳弯曲边框比另一部分更平坦。我们使用3D流体动力模拟研究了超新星残留RCW 103的特殊外围的形成。假设超新星喷射已在具有密度梯度的培养基中进化，则通常可以再现了周围的检测到的形状。对于RCW 103，弹出质量为$ 3.0〜m _ {\ odot} $，背景材料的密度为$ 2.0〜 \ Mathrm {cm}^{ - 3} $，梯度为$ 3.3-4.0〜 \ m atrm {cm}外围通常可以复制。模拟事实证明，SNR RCW 103的不对称性主要是由于具有密度梯度的不均匀培养基。
The young shell-type supernova remnant RCW 103 has peculiar properties in the X-ray morphology obtained with Chandra. The southeastern shell is more brighter in the X-rays, and the curved border of the shell in this region is more flatten than the other part. We investigate the formation of the peculiar periphery of the supernova remnant RCW 103 using 3D hydrodynamical simulation. Assuming that the supernova ejecta has been evolved in the medium with a density gradient, the detected shape of the periphery can be generally reproduced. For RCW 103, with the ejecta mass of $3.0~M_{\odot}$, the density of the background material of $2.0~\mathrm{cm}^{-3}$, and a gradient of $3.3 - 4.0 ~\mathrm{cm}^{-3} \mathrm{pc}^{-1}$, the X-ray periphery can be generally reproduced. The simulation turned out that the asymmetry of the SNR RCW 103 is mainly due to the inhomogeneous medium with a density gradient.
