摘要:

我们提出了我们的搜索新的,扩展的行星状星云(PNe)的基础上仔细,系统,视觉审查的成像数据从INT光度H-阿尔法调查的北银河平面(IPHAS)的第一个结果。新发现的PNe将有助于改善对这一重要的银河系天体群体的普查,这些天体是了解低到中等质量恒星后期演化的关键窗口。他们也将促进研究星系PN光度函数的暗端。IPHAS的灵敏度和覆盖范围允许在银河系中灭绝程度更高的地区发现PNe,和/或与一般银河系PN种群相比,处于更先进进化状态和更远距离的PNe。使用一组新修订的光学诊断图,结合访问功能强大的新的多波长成像数据库,我们已经确定了159个真实的,可能的和可能的PNe。与以前的调查相比,IPHAS能够在银河系低纬度地区和朝向银河系反中心的方向揭示PNe,这使得这次调查成为一个理想的工具,有助于提高我们对整个银河系PN人口的认识

英文摘要:

We present the first results of our search for new, extended Planetary Nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS). The newly uncovered PNe will help to improve the census of this important population of Galactic objects that serve as key windows into the late stage evolution of low to intermediate mass stars. They will also facilitate study of the faint end of the ensemble Galactic PN luminosity function. The sensitivity and coverage of IPHAS allows PNe to be found in regions of greater extinction in the Galactic Plane and/or those PNe in a more advanced evolutionary state and at larger distances compared to the general Galactic PN population. Using a set of newly revised optical diagnostic diagrams in combination with access to a powerful, new, multi-wavelength imaging database, we have identified 159 true, likely and possible PNe for this first catalogue release. The ability of IPHAS to unveil PNe at low Galactic latitudes and towards the Galactic Anticenter, compared to previous surveys, makes this survey an ideal tool to contribute to the improvement of our knowledge of the whole Galactic PN population
