cds-question@unistra.frstar-atlasesinfrared-sourcesearly-type-starsinfrared-astronomyspectroscopyWe present intermediate-resolution (R~8000-12000) high signal-to-noise (S/N) H- and K-band spectroscopy of a sample of 37 optically visible stars, ranging in spectral type from O3 to B3 and representing most luminosity classes. Spectra of this quality can be used to constrain the temperature, luminosity, and general wind properties of OB stars, when used in conjunction with sophisticated atmospheric model codes. Most important is the need for moderately high resolutions (R>=5000) and very high signal-to-noise (S/N>=150) spectra for a meaningful profile analysis. When using near-infrared spectra for a classification system, moderately high signal-to-noise (S/N~100) is still required, though the resolution can be relaxed to just a thousand or two. In the Appendix we provide a set of very high-quality near-infrared spectra of Brackett lines in six early-A dwarfs. These can be used to aid in the modeling and removal of such lines when early-A dwarfs are used for telluric spectroscopic standards.2005ApJS..161..154Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/161/154CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/195 : Optical Spectral Classification OB Stars Atlas (Walborn+ 1990)J/A+AS/105/305 : OB stars observed with high dispersion by IUE (Bohlin+ 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/161/154https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/161/154http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/161/154https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/161/154https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/161/154http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/161/154GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/161/154/table1 (and Observing Data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/161/154/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/161/154/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/161/154/table1?GETtext/xml+votable180.050000true308.3087941.33941750.005555555555555556Cone search capability for table J/ApJS/161/154/table3 (Telluric stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/161/154/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/161/154/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/161/154/table3?GETtext/xml+votable180.050000true30.718648364.90146360.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/ApJS/161/1546/3247 3256 3258 3261 3307 3383 3430 3681 3724 14008 14240 14630 14643 14677 14692 14743 15428 15672 15683 22249 22854 22862 22904 28729 30242 30818 37332 37339 39327 39804 41592 41758 42410 42470 42910 42948 430861.1166583743361574e-19 1.2918781580533825e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/161/154?format=asciiInfrareddefaultJ/ApJS/161/154/table1and Observing DataSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
