| 英文摘要 | We present a sample of metallic-line star (Am) candidates from the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) Data Release One (DR1). According to the characteristic of underabundance of calcium and overabundance of iron element of Am stars, we propose an empirical separation curve derived from line indices of Ca II K line and iron lines we choose for low-resolution spectra. Ultimately, 3537 Am candidates are selected from more than 30 000 stars, which are classified as A-type or early F-type stars by both the LAMOST pipeline and visual inspection. Then, we carry out some analysis on this sample and finally provide a list of the Am candidates with 10 relevant parameters. Compared with other catalogues, Am candidates selected from the LAMOST DR1 are much fainter on the whole. Obviously, our list is an important complement to already known bright Am catalogues, and it offers valuable material for research on this type of chemically peculiar star. |
