论文摘要
行星星云称为猫眼星云（NGC 6543）具有复杂的，点对称的形态，无法通过当前的行星星云形成理论（相互作用的恒星风模型）完全解释。为了揭示猫眼星云的三维（3D）结构，我们使用来自哈勃空间望远镜的[NII]图像和五个不同的位置效率图使用形状代码创建了该星云的详细3D形态模型。这种建模方法揭示了点对称的部分环，这些环很可能是由进攻射流形成的。
The planetary nebula known as the Cat's Eye Nebula (NGC 6543) has a complex, point-symmetric morphology that cannot be fully explained by the current theory of planetary nebula formation, the Interacting Stellar Winds Model. In order to reveal the three dimensional (3D) structure of the Cat's Eye Nebula, we created a detailed 3D morpho-kinematic model of this nebula using a [NII] image from the Hubble Space Telescope and five different position-velocity diagrams using the SHAPE code. This modeling approach has revealed point-symmetric partial rings, which were likely formed by a precessing jet.
