cds-question@unistra.frHD 152219 is a massive binary system with O9.5 III + B1-2 V/III components and a short orbital period of 4.2d. Its primary component further displays clear line profile variability (LPV). The primary component being located within the pulsational instability domain predicted for high-luminosity stars, we previously suggested that the observed LPV could be associated with non-radial pulsations. The aim of the present work is to determine the nature of the observed LPV in the spectrum of the primary component of HD 152219. During a 4-night FEROS monitoring campaign, we collected a new set of 134 high signal-to-noise spectra. These new observations were then used to re-investigate the variability of different line profiles in the spectrum of HD~152219. Based on the present analysis, we discard the non-radial pulsations and point out the Rossiter-McLaughlin effect as the cause of the LPV in HD 152219. The upper limit on the amplitude of possible weak pulsations is set at a few parts per thousand of the continuum level.2009A&A...501..291Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/501/291CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/386/447 : RV catalogue of O-type stars in NGC 6231 (Sana+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/501/291https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/501/291http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/501/291https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/501/291https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/501/291http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/501/291GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/501/291/table2Journal the spectroscopic observations and RV measurements of HD 152219recnoRecord number assigned by the VizieR team.
