cds-question@unistra.frwolf-rayet-starsphotometryWe expect the evolution of massive stars to be strongly influenced by mass loss and hence to be sensitive to metallicity. It should be possible to test this "Conti scenario" be comparing the populations of evolved massive stars among the Local Group galaxies, but such investigations have been hampered by incompleteness. In a previous paper, we presented results of a new survey for red supergiants (RSGs) in selected regions of the Local Group galaxies M33, M31, and NGC 6822. In the present paper, we survey eight fields in M33 for Wolf-Rayet stars (WRs), using interference-filter imaging with a CCD to select candidates. Follow-up spectroscopy is used to confirm 22 newly found WR stars, 21 of WN type. We establish that our survey would readily detect WRs as weak-lined as any known, and we conclude that our survey is essentially complete.1998ApJ...505..793Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/505/793CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/110/2715 : UBV photometry in NGC 6822, M31 and M33 (Massey+ 1995)Table 1: Survey fieldshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/505/793https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/505/793http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/505/793https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/505/793https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/505/793http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/505/793GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/505/793/table2 (WR candidates in M33)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/505/793/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/505/793/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/505/793/table2?GETtext/xml+votable180.050000true23.745416730.69141670.005555555555555556Cone search capability for table J/ApJ/505/793/table9 (Wolf-Rayet stars in M33)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/505/793/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/505/793/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/505/793/table9?GETtext/xml+votable180.050000true23.15662530.66783330.005555555555555556Cone search capability for table J/ApJ/505/793/table10 (Wolf-Rayet stars in M31, IC10, NGC6822 and IC1613 (tables 10, 11 and 12 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/505/793/table10?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/505/793/table10?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/505/793/table10?GETtext/xml+votable180.050000true9.795833340.63794440.0055555555555555566/2154 2155 2240 2241 2622 2623 2666 2708 2709 2752 3042 18041 29718https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/505/793?format=asciiOpticaldefaultJ/ApJ/505/793/table2WR candidates in M33FieldField designationmeta.id;meta.maincharComComments (5)meta.notecharrecnoRecord number assigned by the VizieR team.
