cds-question@unistra.frvariable-starsbe-starsspectroscopyHD 50138 presents the B[e] phenomenon, but its nature is not clear yet. This star is known to present spectral variations, which have been associated with outbursts and shell phases. We analyze the line profile variability of HD 50138 and its possible origin, which provide possible hints to its evolutionary stage, so far said to be close to the end of (or slightly beyond) the main sequence.2012A&A...548A..13Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/548/A13CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/508/309 : Spectral atlas of HD 50138 (Borges Fernandes+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/548/A13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/548/A13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/548/A13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/548/A13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/548/A13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/548/A13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/548/A13/listList of spectrarecnoRecord number assigned by the VizieR team.
