cds-question@unistra.frpeculiar-variable-starssupergiant-starslate-type-starsinterferometryThe mass loss from massive stars is not understood well. eta Carinae is a unique object for studying the massive stellar wind during the luminous blue variable phase. It is also an eccentric binary with a period of 5.54yr. The nature of both stars is uncertain, although we know from X-ray studies that there is a wind-wind collision whose properties change with orbital phase. We want to investigate the structure and kinematics of eta Car's primary star wind and wind-wind collision zone with a high spatial resolution of ~6mas (~14au) and high spectral resolution of R=12000. Observations of eta Car were carried out with the ESO Very Large Telescope Interferometer (VLTI) and the AMBER instrument between approximately five and seven months before the August 2014 periastron passage. Velocity-resolved aperture-synthesis images were reconstructed from the spectrally dispersed interferograms. Interferometric studies can provide information on the binary orbit, the primary wind, and the wind collision.2016A&A...594A.106Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/594/A106CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/163/173 : UV spectrum of eta Car in 2003.5 (Gull+, 2006)J/ApJS/168/289 : NUV spectrum of eta Car in 2003.5 (Nielsen+, 2007)J/ApJS/181/473 : Analysis of the spectrum of {eta} Car (Nielsen+, 2009)J/A+A/540/A133 : {eta} Car emission spectrum (1700-10400{AA}) (Zethson+, 2012)J/AJ/150/109 : Spectroscopy of {eta} Car in 2009 (Richardson+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/594/A106https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/594/A106http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/594/A106https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/594/A106https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/594/A106http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/594/A106GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/594/A106/list (List of fits reconstructed images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/594/A106/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/594/A106/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/594/A106/list?GETtext/xml+votable180.050000true161.26479-4.684450.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/594/A1066/26838https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/594/A106?format=asciidefaultJ/A+A/594/A106/listList of fits reconstructed imagesrecnoRecord number assigned by the VizieR team.
