cds-question@unistra.frmagellanic-cloudsinfrared-sourcesinfrared-astronomyspectroscopyWe performed a near-infrared spectroscopic survey toward an area of ~10deg^2^ of the Large Magellanic Cloud (LMC) with the infrared satellite AKARI. Observations were carried out as part of the AKARI Large-area Survey of the Large Magellanic Cloud (LSLMC). The slitless multi-object spectroscopic capability of the AKARI/IRC enabled us to obtain low-resolution (R~20) spectra in 2-5{mu}m for a large number of point sources in the LMC. As a result of the survey, we extracted about 2000 infrared spectra of point sources. The data are organized as a near-infrared spectroscopic catalog. The catalog includes various infrared objects such as young stellar objects (YSOs), asymptotic giant branch (AGB) stars, supergiants, and so on. It is shown that 97% of the catalog sources have corresponding photometric data in the wavelength range from 1.2 to 11{mu}m, and 67% of the sources also have photometric data up to 24{mu}m. The catalog allows us to investigate near-infrared spectral features of sources by comparison with their infrared spectral energy distributions. In addition, it is estimated that about 10% of the catalog sources are observed at more than two different epochs. This enables us to study a spectroscopic variability of sources by using the present catalog. Initial results of source classifications for the LSLMC samples are presented. We classified 659 LSLMC spectra based on their near-infrared spectral features by visual inspection. As a result, it is shown that the present catalog includes 7 YSOs, 160 C-rich AGBs, 8 C-rich AGB candidates, 85 O-rich AGBs, 122 blue and yellow supergiants, 150 red super giants, and 128 unclassified sources. Distributions of the classified sources on the color-color and color-magnitude diagrams are discussed in the text. Continuous wavelength coverage and high spectroscopic sensitivity in 2-5{mu}m can only be achieved by space observations. This is an unprecedented large-scale spectroscopic survey toward the LMC in the near-infrared. A large number of near-infrared spectral data provided by the survey possess scientific potential that can be applied to various studies. In this paper, we present the details of the spectroscopic survey and the catalog, and discuss its scientific applications.2013AJ....145...32Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/32CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/305 : SAGE LMC and SMC IRAC Source Catalog (IPAC 2009)J/PASP/122/683 : SAGE-Spec Spitzer legacy program (Kemper+, 2010)J/AJ/144/179 : AKARI-LMC Point-source catalog (Kato+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/145/32https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/145/32http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/145/32https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/145/32https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/145/32http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/145/32GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/145/32/sourceli (Source list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/145/32/sourceli?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/145/32/sourceli?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/145/32/sourceli?GETtext/xml+votable180.050000true77.3982911-67.32997890.005555555555555556AKARI5/8273 8274 8275 8278 6/33089 33090 33091 33106 33116 33121 33124 331251.0763920601544068e-21 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/145/32?format=asciiInfrareddefaultJ/AJ/145/32/sourceliSource listDEJ2000Declination (J2000)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
