cds-question@unistra.frbe-starsvariable-starsvisible-astronomymedium-band-photometryspectroscopyWe present results of nearly simultaneous monitoring of uvby light and HeI667.81nm line-profile variations of the equatorial Be star DX Eri in November 1991. They are analysed along with numerous uvby photometry in the period 1986-1995.1996A&A...309..787Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/309/787CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/309/787https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/309/787http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/309/787https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/309/787https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/309/787http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/309/787GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/309/787/table1La Silla photometric observations, November 1991recnoRecord number assigned by the VizieR team.
