论文摘要
我们介绍了双极行星星云（PN）IPHASTX J191104.8 $+$+$ 060845（PN G040.6 $ -01.5）的首次详细研究，作为ISAAC Newton望远镜光度H $α$调查的北部银色银河平面调查（ISAAC Newton Telescope Hus）的一部分。我们提出北欧光学望远镜（非）窄带图像，以揭示其真实的形态。该PN由一个主腔组成，其两个新发现的延伸的低表面亮度裂片位于西北和SE方向。使用近红外图像，我们揭示了围绕着主腔的桶形结构的存在，这将解释朝向赤道区域的黑暗车道。我们还使用Gran Telescopio de Canarias（GTC）光谱来研究该PN的物理特性。我们强调了在IPHAS中检测到的旧PNE的潜力，以研究围绕太阳能恒星的偶然介质演变的最后阶段。
We present the first detailed study of the bipolar planetary nebula (PN) IPHASX J191104.8$+$060845 (PN G040.6$-$01.5) discovered as part of the Isaac Newton Telescope Photometric H$α$ Survey of the Northern Galactic plane (IPHAS). We present Nordic Optical Telescope (NOT) narrow-band images to unveil its true morphology. This PN consists of a main cavity with two newly uncovered extended low-surface brightness lobes located towards the NW and SE directions. Using near-IR WISE images we unveiled the presence of a barrel like structure, which surrounds the main cavity, which would explain the dark lane towards the equatorial regions. We also use Gran Telescopio de Canarias (GTC) spectra to study the physical properties of this PN. We emphasise the potential of old PNe detected in IPHAS to study the final stages of the evolution of the circumstellar medium around solar-like stars.
