论文摘要
我们提出的目录为3,305 h $α$发射线点源，其中大型天空区域多对象纤维光谱望远镜（lamost）在2011年9月和2016年1月的M31和M33附近领域中观察到的目录。 83 H〜 {\ textsc {ii}}区域候选和20个可能的超新星残留物（SNR）和1,286个未知对象。其中，有24名PN候选者，19 H〜 {\ sc II}地区候选人，10名SNR候选人和1名共生星候选人是新发现。从H $α$线估算的径向速度和通量以及其他七个主要排放线的量[n〜 {\ textsc {ii}}]〜$λ$ 6548，[n〜 {\ textsc {ii}}]我们的目录中还介绍了从Lamost光谱中屈服的。我们的目录是研究M31和M33的化学特性和运动学特性的理想起点。
We present a catalogue of 3,305 H$α$ emission-line point sources observed with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in the vicinity fields of M31 and M33 during September 2011 and January 2016. The catalogue contains 1,487 emission-line stars, 532 emission-line nebulae including 377 likely planetary nebulae (PNe), 83 H~{\textsc{ii}} regions candidates and 20 possible supernovae remnants (SNRs) and 1,286 unknown objects. Among them, 24 PN candidates, 19 H~{\sc ii} region candidates, 10 SNR candidates and 1 symbiotic star candidate are new discoveries. Radial velocities and fluxes estimated from the H$α$ line and those quantities of seven other major emission lines including H$β$, [O~{\textsc{iii}}]~$λ$4959, [O~{\textsc{iii}}]~$λ$5007, [N~{\textsc{ii}}]~$λ$6548, [N~{\textsc{ii}}]~$λ$6583, [S~{\textsc{ii}}]~$λ$6717 and [S~{\textsc{ii}}]~$λ$6731 lines of all the catalogued sources yielded from the LAMOST spectra are also presented in our catalogue. Our catalogue is an ideal starting point to study the chemistry properties and kinematics of M31 and M33.
