摘要:

我们提供了2011年9月至2016年1月期间在M31和M33附近区域使用大天区多目标光纤光谱望远镜(LAMOST)观测到的3,305 H $α$发射线点源目录。该星表包含1,487颗发射线星,532个发射线星云,其中包括377个可能的行星状星云(PNe),83个H~{ \textsc{ii} }区候选者,20个可能的超新星遗迹(SNRs)和1,286个未知天体。其中24颗PN候选星、19颗H~{ \sc ii}区候选星、10颗SNR候选星和1颗共生星候选星为新发现。根据H $α$谱线和其他七条主要发射谱线H $β$,[O~{ \textsc{iii} }]~ $λ$ 4959,[O~{\textsc{iii}}]~ $λ$ 5007,[N~{ \textsc{ii} }]~ $λ$ 6548,[N~{\textsc{ii}}]~ $λ$ 6583,我们的星表还列出了由LAMOST谱产生的所有编目源的[S~{\textsc{ii}}]~ $λ$ 6717和[S~{ \textsc{ii} }]~ $λ$ 6731线。我们的目录是研究M31和M33的化学性质和运动学的理想起点。

英文摘要:

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.
