论文摘要
我们分析了在1998年，2001年和2002年观察到的共生Nova Ag Peg的高色散发射线。H$α$和H $β$线显示了三个组件，两个组件，两个狭窄和一个基本的宽线组件，但大多数其他线条，例如HI，HEI和HEI，HEI和HEII线条，仅显示两种蓝色和红色的组合。 Lee＆Hyung（2018）最近的一项研究表明，双极圆锥外壳发出的双高斯线可能形成1998年观察到的拉曼散射线。在这项研究中，我们表明，带有74 $^{o} $的开头角度的双极锥，在70 kms $^a的$^n Conder and parterf and parterf的范围内，均可膨胀。 1998年，2001年和2002年的双线轮廓。我们得出的结论是，由于积聚盘的准确性，沿着白矮人的双极轴形成的双极圆锥壳的发射区是造成双层高斯轮廓的原因。
We analyze high dispersion emission lines of the symbiotic nova AG Peg, observed in 1998, 2001, and 2002. The H$α$ and H$β$ lines show three components, two narrow and one underlying broad line components, but most other lines, such as HI, HeI, and HeII lines, show two blue- and red-shifted components only. A recent study by Lee & Hyung (2018) suggested that the double Gaussian lines emitted from a bipolar conic shell is likely to form Raman scattering lines observed in 1998. In this study, we show that the bipolar cone with an opening angle of 74$^{o}$, which expands at a velocity of 70 kms$^{-1}$ along the polar axis of the white dwarf, can accommodate the observed double line profiles in 1998, 2001, and 2002. We conclude that the emission zone of the bipolar conic shell, which formed along the bipolar axis of the white dwarf due to the collimation by the accretion disk, is responsible for the double Gaussian profiles.
