Spectroscopic study of Herbig Ae/Be stars in the Galactic anti-centre region from LAMOST DR5

Abstract: We study a sample of 119 Herbig Ae/Be stars in the Galactic anti-center direction using the spectroscopic data from Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST) survey program. Emission lines of hydrogen belonging to the Balmer and Paschen series, and metallic lines of species such as Fe ii, O i, Ca ii triplet are identified. A moderate correlation is observed between the emission strengths of Hα and Fe ii 5169 Å, suggesting a possible common emission region for Fe ii lines and one of the… Show more
