cds-question@unistra.frearly-type-starsbe-starsinfrared-astronomyspectroscopyWe present a digital atlas of peculiar, high-luminosity massive stars in the near-infrared region (10470-11000{AA}) at medium resolution (R~7000). The spectra are centered around HeI 10830{AA}, which is formed in the wind of those stars, and is a crucial line to obtain their physical parameters. The instrumental configuration also sampled a rich variety of emission lines of FeII, MgII, CI, NI, and Pa{gamma}. Secure identifications for most spectral lines are given, based on synthetic atmosphere models calculated by our group. We also propose that two unidentified absorption features have interstellar and/or circumstellar origin. For the strongest one (10780{AA}) an empirical calibration between E(B-V) and equivalent width is provided. The atlas displays the spectra of massive stars organized in four categories, namely Be stars, OBA Iape (or luminous blue variables, LBV candidates and ex/dormant LBVs), OB supergiants and Wolf-Rayet stars. For comparison, the photospheric spectra of non emission-line stars are presented. Selected LBVs were observed in different epochs from 2001 to 2004, and their spectral variability reveals that some stars, such as eta Car, AG Car and HR Car, suffered dramatic spectroscopic changes during this time interval.2007A&A...465..993Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/465/993CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/465/993https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/465/993http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/465/993https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/465/993https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/465/993http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/465/993GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/465/993/table1 (Basic data for the program stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/465/993/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/465/993/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/465/993/table1?GETtext/xml+votable180.050000true58.8462531.0458330.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/465/9936/1196 13268 14646 14649 20764 21365 28726 28804 28831 29116 29162 30694 30722 31759 37339 37362 37841 37930 38016 39216 42206 42273 42296 42383 42387 42394 42405 42416 42477 43024 43310 43365 43531 44360 44502 47121https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/465/993?format=asciiInfrareddefaultJ/A+A/465/993/table1Basic data for the program starsHD?
