cds-question@unistra.frmultiple-starsinfrared-photometryOur new near-infrared J and Ks-band images taken towards IRAS 06468-0325 revealed the presence of extended emission with very unusual and enigmatic morphology: that of a diamond-ring, that is, a ring or torus with a bright source overlaping the edge of it (not inside it). We report the discovery of this source, explore its nature, and propose possible interpretations of its morphological structure. We observed IRAS 06468-0325 obtaining optical and infrared images through IJHKs and L' filters, K-band low-resolution spectroscopy, together with millimetre line observations of CO(1-0), ^13^CO(2-1), C^18^O(2-1), and CS(2-1).2007A&A...470..231Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/470/231CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/470/231https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/470/231http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/470/231https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/470/231https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/470/231http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/470/231GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/470/231/table1 (Photometry of IRAS 06468-0325)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/470/231/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/470/231/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/470/231/table1?GETtext/xml+votable180.050000true102.34625-3.4816670.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/470/2316/220655.0692151230857684e-20 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/470/231?format=asciiInfrareddefaultJ/A+A/470/231/table1Photometry of IRAS 06468-0325HimName of the FITS imagemeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
