About 35 much fainter (mostly between R=16 and >21) H{alpha} emitters have been found in the cloud. Their color-magnitude distribution suggests a median age of about 0.5Myr, with considerable dispersion. There are also at least five bright B-type stars in the cloud, presumably of about the same age; none show the peculiarities expected of HAeBe stars. Dereddened, their apparent V magnitudes lead to a distance of about 700pc. Radio observations suggest that the optical object LkH{alpha} 101 is in fact a hot star surrounded by a small H II region, both inside an optically thick dust shell.2004AJ....128.1233Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/128/1233CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/128/1233https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/128/1233http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/128/1233https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/128/1233https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/128/1233http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/128/1233GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/128/1233/table1 (Optical and near-infrared photometry of stars in NGC 1579)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/1233/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/1233/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/1233/table1?GETtext/xml+votable180.050000true67.475535.25550.005555555555555556Cone search capability for table J/AJ/128/1233/table4 (Coordinates and Lick UBV photometry of bright stars in L1482)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/1233/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/1233/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/1233/table4?GETtext/xml+votable180.050000true67.36916735.2219440.0055555555555555566/1231https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/128/1233?format=asciiOpticalInfrareddefaultJ/AJ/128/1233/table1Optical and near-infrared photometry of stars in NGC 1579Jmag?
