M-type stars in LAMOST DR5 J/ApJS/244/8 ivo://CDS.VizieR/J/ApJS/244/8 doi:10.26093/cds/vizier.22440008 CDS Zhong J. Li J. Carlin J.L. Chen L. Mendez R.A.

In total, 39796 M giants and 501152 M dwarfs are identified from the classification pipeline. The template-fitting results contain M giants with 7 temperature subtypes from M0 to M6, M dwarfs with 18 temperature subtypes from K7.0 to M8.5, and 12 metallicity subclasses from dMr to usdMp. We cross-matched our M-type catalog with the Two Micron All-Sky Survey (2MASS) and Wide-field Infrared Survey Explorer (WISE) catalog to obtain infrared magnitude and colors. Adopting the distances derived from the parallaxes in Gaia DR2, the M_G_ versus (G_bp_-G_rp_)_0_ diagram shows that there are also early-type stars and white dwarf-M dwarf binaries included in our M-type stars sample, with a contamination rate of about 4.6% for M giants and 0.48% for M dwarfs. We found that CaH spectral indices are an efficient selection criteria for carbon stars. A total of 289 carbon stars were identified from the M giants sample, and further confirmed by LAMOST spectra. 2019ApJS..244....8Z https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/244/8 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997) II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+, 2003) II/328 : AllWISE Data Release (Cutri+, 2013) I/345 : Gaia DR2 (Gaia, 2018) I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018) V/153 : LAMOST DR4 catalogs (Luo+, 2018) V/164 : LAMOST DR5 catalogs (Luo+, 2019) J/AJ/128/1177 : Galactic stellar abundances (Venn+, 2004) J/ApJ/670/346 : M giant stars in the Sagittarius dwarf galaxy.
