Ha emission-line stars & Herbig Ae/Be from LAMOST J/ApJS/259/38 ivo://CDS.VizieR/J/ApJS/259/38 doi:10.26093/cds/vizier.22590038 CDS Zhang Y.-J. Hou W. Luo A.-L. Li S. Qin L. Lu Y. Li Y.-B.

The spectra are classified into three morphological types (10 subtypes) based on H{alpha} emission-line profiles. Some spectra contaminated by nebula emission lines such as from HII regions are flagged in the catalog. We also provide a specific catalog of 20 stars with stellar winds or accretion flows by calculating the terminal and peak velocities based on P-Cygni or inverse P-Cygni profiles. More important, with two color-color diagrams, (H-Ks, J-H) and (Ks-W1, H-Ks), of a collection of known Herbig Ae/Be stars (HAeBes) and classical Ae/Be stars (CAeBes), we propose an updated criterion to separate HAeBes from CAeBes. By the criterion, we select 118 HAeBe candidates and 2636 CAeBe candidates from the sample. We confirm 71 of the 118 HAeBes based on the data from LAMOST (optical spectra) and WISE (photometry and images), 62 of which are newly identified. The 71 identified HAeBes are compiled into a specific catalog, and their SEDs and MIR images are also presented. The distances of 76% confirmed HAeBes are further than 1kpc, which enlarges the number of known HAeBes in further distance. Most of the 71 HAeBes are located in the Galactic disk while 6 of them have |Zgal|>400pc. Four HAeBes show the forbidden emission lines of [FeII] and [OI], in which J051425.20+411310.7 is a newly discovered B[e]. In addition, four HAeBes having Spitzer IRS spectra all show PAH features. 2022ApJS..259...38Z https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/259/38 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003) II/297 : AKARI/IRC mid-IR all-sky Survey (ISAS/JAXA, 2010) I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018) I/345 : Gaia DR2 (Gaia Collaboration, 2018) II/360 : Gaia DR2 x AllWISE catalogue (Marton+, 2019) VII/7 : Lynds' Catalogue of Dark Nebulae (LDN) (Lynds 1962) VII/21 : Catalogue of Reflection Nebulae (Van den Bergh, 1966) V/146 : LAMOST DR1 catalogs (Luo+, 2015) V/164 : LAMOST DR5 catalogs (Luo+, 2019) V/156 : LAMOST DR7 catalogs (Luo+, 2019) J/A+AS/104/315 : Member of Herbig Ae/Be stellar group (The+ 1994) J/A+AS/113/325 : Distance measurements of Lynds Nebulae (Hilton+, 1995) J/AJ/117/354 : OB associations from Hipparcos (de Zeeuw+, 1999) J/AJ/126/2971 : UBVRI photometry of 131 Herbig Ae/Be (Vieira+, 2003) J/A+A/417/263 : Catalogue of Algol type binary stars (Budding+, 2004) J/AJ/129/856 : Herbig Ae/Be stars in nearby OB assoc.
