cds-question@unistra.frwolf-rayet-starsccd-photometryWhat is the origin of the large-amplitude variability in Wolf-Rayet WN8 stars in general and WR123 in particular? A dedicated spectroscopic campaign targets the ten-hour period previously found in the high-precision photometric data obtained by the MOST satellite. In June-August 2003 we obtained a series of high signal-to-noise, mid-resolution spectra from several sites in the {lambda}{lambda}4000-6940{AA} domain. We also followed the star with occasional broadband (Johnson V) photometry. The acquired spectroscopy allowed a detailed study of spectral variability on timescales from ~5 minutes to months.2011A&A...530A.151Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/530/A151CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/530/A151https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/530/A151http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/530/A151https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/530/A151https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/530/A151http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/530/A151GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/530/A151/fig1Light curve of WR 123 obtained at Bell Observatory in 2003recnoRecord number assigned by the VizieR team.
