cds-question@unistra.fremission-line-starssupergiant-starsspectroscopyinfrared-astronomyB[e] supergiants are evolved massive stars, enshrouded in a dense wind and surrounded by a molecular and dusty disk. The mechanisms that drive phases of enhanced mass loss and mass ejections, responsible for the shaping of the circumstellar material of these objects, are still unclear. We aim to improve our knowledge on the structure and dynamics of the circumstellar disk of the Large Magellanic Cloud B[e] supergiant LHA 120-S 73. High-resolution optical and near-infrared spectroscopic data were obtained over a period of 16 and 7 yr, respectively. The spectra cover the diagnostic emission lines from [CaII] and [OI], as well as the CO bands. These features trace the disk at different distances from the star. We analyzed the kinematics of the individual emission regions by modeling their emission profiles. A low-resolution mid-infrared spectrum was obtained as well, which provides information on the composition of the dusty disk.2016A&A...593A.112Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/593/A112CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/593/A112https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/593/A112http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/593/A112https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/593/A112https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/593/A112http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/593/A112GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/593/A112/listList of spectrarecnoRecord number assigned by the VizieR team.
