盱眙反银心方向2000平方度Halpha窄波段观测

The international Halpha narrow-band survey carried out is limited by the small sky area or low resolution. There is no even related survey in China. So we first introduced the Halpha narrow-band survey of small sky area in the Galactic anti-center direction. It can be served as a basis work for future large area survey. This project is mainly about the survey of about 2000 square degrees of the Galactic anti-center with Halpha narrow-band filter based on the XuYi Near Earth Object Survey Telescope. The results of this survey includes the catalog of Halpha narrow-band filter, the catalog of Halpha emission line objects and the maps of Halpha narrow-band survey. According to the study of these Halpha emission line objects, it is very helpful for studying the star formation, evolution of stars, measuring star formation rate of extragalactic and so on.

目前国际上开展的Halpha窄波段观测项目或是天区面积小，或是分辨率低，而国内更是没有相关的观测。因此，我们首先提出了银河系反银心方向小天区的Halpha窄波段观测，同时为以后大的巡天工作做基础。该项目主要是基于盱眙近地天体望远镜，利用Halpha窄波段滤光片对银河系反银心的约2000平方度天区进行观测，通过对大量观测数据的处理最终给出该天区的Halpha窄波段观测星表、Halpha发射线天体星表以及Halpha窄波段图像。通过对Halpha发射线天体的观测，对我们研究恒星形成和演化、测量河外星系的恒星形成率、共生星以及一些活动星等等有着重大意义。

目前国内外开展的天文巡天观测大都是宽带或光谱巡天，而窄波段的测光巡天是屈指可数 ，主要以IPHAS和PTF的Halpha巡天为主。IPHAS DR2已经释放，然而PTF的窄带数据迟迟没有消 息。于是我们结合IPHAS的窄带数据提出了北天区银盘的[SII]窄波段巡天观测(S-NBS)。该项 目主要是基于紫金山天文台盱眙观测站的近地天体望远镜，利用[SII]窄波段滤光片对北天区 银纬正负5度以内的银盘区域进行观测，与IPHAS天区重合，面积约1800平方度。[SII]结合该 天区已释放的r, i宽带数据和Halpha窄带数据，为研究银盘区域的激波现象、HII区、超新星 遗迹以及行星状星云等有着重大意义。
