cds-question@unistra.frvariable-starsline-intensitiesradial-velocityWe report the discovery of two new Galactic candidate luminous blue variable (LBV) stars via detection of circular shells (typical of confirmed and candidate LBVs) and follow-up spectroscopy of their central stars. The shells were detected at 22um in the archival data of the Mid-Infrared All Sky Survey carried out with the Wide-field Infrared Survey Explorer (WISE). Follow-up optical spectroscopy of the central stars of the shells conducted with the renewed Southern African Large Telescope (SALT) showed that their spectra are very similar to those of the well-known LBVs P Cygni and AG Car, and the recently discovered candidate LBV MN112, which implies the LBV classification for these stars as well.2012MNRAS.421.3325Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/421/3325CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/421/3325https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/421/3325http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/421/3325https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/421/3325https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/421/3325http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/421/3325GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/421/3325/table4 (Details of central stars associated with two circular shells discovered with WISE)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/421/3325/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/421/3325/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/421/3325/table4?GETtext/xml+votable180.050000true204.1192917-63.760750.0055555555555555566/41673 424848.157980699529898e-21 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/421/3325?format=asciiOpticaldefaultJ/MNRAS/421/3325/table4Details of central stars associated with two circular shells discovered with WISErecnoRecord number assigned by the VizieR team.
